One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital audio processors and MPEG decoders. The device accepts a wide range of input data and data rates. A fully programmable data path routes these channels to the internal speaker drivers. The TAS5717/9 is a slave-only device receiving all clocks from external sources. The TAS5717/TAS5719 operates with a PWM carrier between a 384-kHz switching rate and a 352-KHz switching rate, depending on the input sample rate. Oversampling combined with a fourth-order noise shaper provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz. 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

An internal voltage regulator provides suitable voltage levels for the gate drive circuitry. Additionally, all circuitry requiring a floating voltage supply, e.g., the high-side gate drive, is accommodated by built-in bootstrap circuitry requiring only a few external capacitors. In order to provide good electrical and acoustical characteristics, the PWM signal path for the output stage is designed as identical, independent half-bridges. For this reason, each half-bridge has separate bootstrap pins (BST_X) and power-stage supply pins (PVDD_X). The gate drive voltages (GVDD_AB and GVDD_CD) are derived from the PVDD voltage. Special attention should be paid to placing all decoupling capacitors as close to their associated pins as possible. In general, inductance between the power-supply pins and decoupling capacitors must be avoided. For a properly functioning bootstrap circuit, a small ceramic capacitor must be connected from each bootstrap pin (BST_X) to the power-stage output pin (OUT_X). When the power-stage output is low, the bootstrap capacitor is charged through an internal diode connected between the gate-drive regulator output pin (GVDD_X) and the bootstrap pin. When the power-stage output is high, the bootstrap capacitor potential is shifted above the output potential and thus provides a suitable voltage supply for the high-side gate driver. In an application with PWM switching frequencies in the range from 352 kHz to 384 kHz, it is recommended to use 33-nF ceramic capacitors, size 0603 or 0805, for the bootstrap supply. These 33-nF capacitors ensure sufficient energy storage, even during minimal PWM duty cycles, to keep the high-side power stage FET (LDMOS) fully turned on during the remaining part of the PWM cycle. Special attention should be paid to the power-stage power supply; this includes component selection, PCB placement, and routing. As indicated, each half-bridge has independent power-stage supply pins (PVDD_X). For optimal electrical performance, EMI compliance, and system reliability, it is important that each PVDD_X pin is decoupled with a 100-nF ceramic capacitor placed as close as possible to each supply pin. The TAS5717/9 is fully protected against erroneous power-stage turnon due to parasitic gate charging. I2C CHIP SELECT/HP_SHUTDOWN A_SEL/HP_SD is an input pin during power up. It can be pulled high or low. HIGH indicates an I2C subaddress of 0x56, and LOW a subaddress of 0x54. DEVICE PROTECTION SYSTEM Overcurrent (OC) Protection With Current Limiting The device has independent, fast-reacting current detectors on all high-side and low-side power-stage FETs. The detector outputs are closely monitored a protection system. If the high-current condition situation persists, i.e., the power stage is being overloaded, a protection system triggers a latching shutdown, resulting in the power stage being set in the high-impedance (Hi-Z) state. The device returns to normal operation once the fault condition (i.e., a short circuit on the output) is removed. Current limiting and overcurrent protection are not independent for half-bridges. That is, if the bridge-tied load between half-bridges A and B causes an overcurrent fault, half-bridges A, B, C, and D are shut down. Overtemperature Protection The TAS5717/9 has an overtemperature-protection system. If the device junction temperature exceeds 150°C (nominal), the device is put into thermal shutdown, resulting in all half-bridge outputs being set in the high-impedance (Hi-Z) state and FAULT being asserted low. The TAS5717/9 recovers automatically once the temperature drops approximately 30°. 20 Submit Documentation Feedback © 2010–2011, Texas Instruments Incorporated Product Folder Link(s): TAS5717 TAS5719 TAS5717 TAS5719 SLOS655A – NOVEMBER 2010 – REVISED FEBRUARY 2011 www.ti.com Undervoltage Protection (UVP) and Power-On Reset (POR) The UVP and POR circuits of the TAS5717/9 fully protect the device in any power-up/down and brownout situation. While powering up, the POR circuit resets the overload circuit (OLP) and ensures that all circuits are fully operational when the PVDD and AVDD supply voltages reach 4.5 V and 2.7 V, respectively. Although PVDD and AVDD are independently monitored, a supply voltage drop below the UVP threshold on AVDD or on either PVDD pin results in all half-bridge outputs immediately being set in the high-impedance (Hi-Z) state and FAULT being asserted low. CLOCK, AUTO DETECTION, AND PLL The TAS5717/9 is a slave device. It accepts MCLK, SCLK, and LRCLK. The digital audio processor (DAP) supports all the sample rates and MCLK rates that are defined in the clock control register . The TAS5717/9 checks to verify that SCLK is a specific value of 32 fS, 48 fS, or 64 fS. The DAP only supports a 1 × fS LRCLK. The timing relationship of these clocks to SDIN is shown in subsequent sections. The clock section uses MCLK or the internal oscillator clock (when MCLK is unstable, out of range, or absent) to produce the internal clock (DCLK) running at 512 times the PWM switching frequency. The DAP can autodetect and set the internal clock-control logic to the appropriate settings for all supported clock rates as defined in the clock control register. TAS5717/9 has robust clock error handling that uses the bulit-in trimmed oscillator clock to quickly detect changes/errors. Once the system detects a clock change/error, it mutes the audio (through a single-step mute) and then forces PLL to limp using the internal oscillator as a reference clock. Once the clocks are stable, the system autodetects the new rate and reverts to normal operation. During this process, the default volume is restored in a single step (also called hard unmute). The ramp process can be programmed to ramp back slowly (also called soft unmute) as defined in volume register (0x0E). SERIAL DATA INTERFACE Serial data is input on SDIN. The PWM outputs are derived from SDIN. The TAS5717/9 DAP accepts serial data in 16-, 20-, or 24-bit left-justified, right-justified, or I2S serial data format. PWM Section The TAS5717/9 DAP device uses noise-shaping and sophisticated nonlinear correction algorithms to achieve high power efficiency and high-performance digital audio reproduction. The DAP uses a fourth-order noise shaper to increase dynamic range and SNR in the audio band. The PWM section accepts 24-bit PCM data from the DAP and outputs two BTL PWM audio output channels. The PWM section has individual-channel dc-blocking filters that can be enabled and disabled. The filter cutoff frequency is less than 1 Hz. Individual-channel de-emphasis filters for 44.1- and 48-kHz are included and can be enabled and disabled. Finally, the PWM section has an adjustable maximum modulation limit of 93.8% to 99.2%. For detailed description of using audio processing features like DRC and EQ, see the User's Guide and TAS570X GDE software development tool documentation. Also see the GDE software development tool for the device data path. I2C COMPATIBLE SERIAL CONTROL INTERFACE The TAS5717/9 DAP has an I2C serial control slave interface to receive commands from a system controller. The serial control interface supports both normal-speed (100-kHz) and high-speed (400-kHz) operations without wait states. As an added feature, this interface operates even if MCLK is absent. The serial control interface supports both single-byte and multiple-byte read and write operations for status registers and the general control registers associated with the PWM.

This is a slave-only device that does not support a multimaster bus environment or wait-state insertion. The control interface is used to program the registers of the device and to read device status. The DAP supports the standard-mode I2C bus operation (100 kHz maximum) and the fast I2C bus operation (400 kHz maximum). The DAP performs all I2C operations without I2C wait cycles. General I2C Operation The I2C bus employs two signals; SDA (data) and SCL (clock), to communicate between integrated circuits in a system. Data is transferred on the bus serially, one bit at a time. The address and data can be transferred in byte (8-bit) format, with the most significant bit (MSB) transferred first. In addition, each byte transferred on the bus is acknowledged by the receiving device with an acknowledge bit. Each transfer operation begins with the master device driving a start condition on the bus and ends with the master device driving a stop condition on the bus. The bus uses transitions on the data pin (SDA) while the clock is high to indicate start and stop conditions. A high-to-low transition on SDA indicates a start and a low-to-high transition indicates a stop. Normal data-bit transitions must occur within the low time of the clock period. These conditions are shown in Figure 35. The master generates the 7-bit slave address and the read/write (R/W) bit to open communication with another device and then waits for an acknowledge condition. The TAS5717/9 holds SDA low during the acknowledge clock period to indicate an acknowledgment. When this occurs, the master transmits the next byte of the sequence. Each device is addressed by a unique 7-bit slave address plus R/W bit (1 byte). All compatible devices share the same signals via a bidirectional bus using a wired-AND connection. An external pullup resistor must be used for the SDA and SCL signals to set the high level for the bus.

Typical I2C Sequence There is no limit on the number of bytes that can be transmitted between start and stop conditions. When the last word transfers, the master generates a stop condition to release the bus. A generic data transfer sequence is shown in Figure 35. The 7-bit address for TAS5717/9 is 0101 010 (0x54) or 0101 011 (0x56) defined by A_SEL (external pulldown for 0x54 and pullup for 0x56).Stero device with Headphone should use 0x54 as its device address. Single- and Multiple-Byte Transfers The serial control interface supports both single-byte and multiple-byte read/write operations for subaddresses 0x00 to 0x1F. However, for the subaddresses 0x20 to 0xFF, the serial control interface supports only multiple-byte read/write operations (in multiples of 4 bytes). During multiple-byte read operations, the DAP responds with data, a byte at a time, starting at the subaddress assigned, as long as the master device continues to respond with acknowledges. If a particular subaddress does not contain 32 bits, the unused bits are read as logic 0. During multiple-byte write operations, the DAP compares the number of bytes transmitted to the number of bytes that are required for each specific subaddress. For example, if a write command is received for a biquad subaddress, the DAP expects to receive five 32-bit words. If fewer than five 32-bit data words have been received when a stop command (or another start command) is received, the data received is discarded.

The TAS5717/9 also supports sequential I2C addressing. For write transactions, if a subaddress is issued followed by data for that subaddress and the 15 subaddresses that follow, a sequential I2C write transaction has taken place, and the data for all 16 subaddresses is successfully received by the TAS5717/9. For I2C sequential write transactions, the subaddress then serves as the start address, and the amount of data subsequently transmitted, before a stop or start is transmitted, determines how many subaddresses are written. As was true for random addressing, sequential addressing requires that a complete set of data be transmitted. If only a partial set of data is written to the last subaddress, the data for the last subaddress is discarded. However, all other data written is accepted; only the incomplete data is discarded. Single-Byte Write As shown in Figure 36, a single-byte data-write transfer begins with the master device transmitting a start condition followed by the I2C device address and the read/write bit. The read/write bit determines the direction of the data transfer. For a data-write transfer, the read/write bit is 0. After receiving the correct I2C device address and the read/write bit, the DAP responds with an acknowledge bit. Next, the master transmits the address byte or bytes corresponding to the TAS5717/9 internal memory address being accessed. After receiving the address byte, the TAS5717/9 again responds with an acknowledge bit. Next, the master device transmits the data byte to be written to the memory address being accessed. After receiving the data byte, the TAS5717/9 again responds with an acknowledge bit. Finally, the master device transmits a stop condition to complete the single-byte data-write transfer.

As a result, the read/write bit becomes a 0. After receiving the TAS5717/9 address and the read/write bit, TAS5717/9 responds with an acknowledge bit. In addition, after sending the internal memory address byte or bytes, the master device transmits another start condition followed by the TAS5717/9 address and the read/write bit again. This time the read/write bit becomes a 1, indicating a read transfer. After receiving the address and the read/write bit, the TAS5717/9 again responds with an acknowledge bit. Next, the TAS5717/9 transmits the data byte from the memory address being read. After receiving the data byte, the master device transmits a not-acknowledge followed by a stop condition to complete the single-byte data-read transfer.

Single-Byte Read Transfer Multiple-Byte Read A multiple-byte data-read transfer is identical to a single-byte data-read transfer except that multiple data bytes are transmitted by the TAS5717/9 to the master device as shown in Figure 39. Except for the last data byte, the master device responds with an acknowledge bit after receiving each data byte.

There is one ganged DRC for the high-band left/right channels and one DRC for the low-band left/right channels. The DRC input/output diagram is shown in Figure 40. See the GDE software tool for more description on the T, K, and O parameters. Output Level (dB) K 1:1 Transfer Function Implemented Transfer Function T Input Level (dB) M0091-03 Professional-quality dynamic range compression automatically adjusts volume to flatten volume level. • Each DRC has adjustable threshold levels. • Programmable energy, attack, and decay time constants • Transparent compression: compressors can attack fast enough to avoid apparent clipping before engaging, and decay times can be set slow enough to avoid pumping.

If the most significant bit is logic 0, the number is a positive number, and the weighting shown yields the correct number. If the most significant bit is a logic 1, then the number is a negative number. In this case every bit must be inverted, a 1 added to the result, and then the weighting shown in Figure 44 applied to obtain the magnitude of the negative number. 1 0 2 Bit 2 Bit 1 2 0 –1 Bit (1 or 0) ´ 2 + (1 or 0) ´ 2 + (1 or 0) ´ 2 2 –1 –4 Bit + .......

This means that the software must clear the register (write zeroes) and then read them to determine if they are persistent errors. Error definitions: • MCLK error: MCLK frequency is changing. The number of MCLKs per LRCLK is changing. • SCLK error: The number of SCLKs per LRCLK is changing. • LRCLK error: LRCLK frequency is changing. • Frame slip: LRCLK phase is drifting with respect to internal frame sync.

If 1, the dc-blocking filter (–3 dB cutoff <1 Hz) for each channel is enabled. Bit D5: If 0, use soft unmute on recovery from a clock error. This is a slow recovery. Unmute takes the same time as the volume ramp defined in register 0x0E. If 1, use hard unmute on recovery from clock error. This is a fast recovery, a single-step volume ramp.

The value should be 0x30 for BTL mode and 0x3A for PBTL mode. The default value of this register is 0x30. The functionality of this register is tied to the state of bit D5 in the system control register. This register defines which channels belong to the shutdown group (SDG). If a 1 is set in the shutdown group register, that particular channel is not started following an exit out of all-channel shutdown command (if bit D5 is set to 0 in system control register 2, 0x05).

An audio system can be set up for different applications using this device. Case 1 – Headphone (HP)/Line Drive With Analog Input: The device can be represented as shown in Figure 46: analog inputs (single-ended) as HPL_IN (pin 1) and HPR_IN (pin 4) with the outputs HPL_OUT (pin 2) and HPR_OUT (pin 3). R2 R1 VIN HPL_IN HPL_OUT VOUT S0490-01 Figure 46. Headphone/Line Driver with Analog Input HP_SD pin can be used turn ON/OFF the headphone amplifier/line driver. Speaker channels are independent of headphone/line driver in this mode. Case 2 – Headphone With I2S Input: Hardware setup: The HP_PWML and HP_PWMR signals should be fed into a low-pass filter (LPF), and the output of the LPF is fed to analog inputs (HPL_IN and HPR_IN). The A_SEL pin has a 15-kΩ pulldown to ground and should be routed to headphone amplifier enable (HP_SDZ pin 33). Software setup: Write to register 0x05 bits D4 = 1, D1 = 1, and D0 = 1 (13 hex). When D4 and D1 are set to 1, the A_SEL pin goes high and thus enables the headphone output. When register 0x05 D4 = 1, the device is in headphone mode and the speaker outputs are in shutdown. NOTE: The speaker and headphone cannot be used at the same time as they both share the same digital channel. DAP can be used for headphone volume. 56 Submit Documentation Feedback © 2010–2011, Texas Instruments Incorporated Product Folder Link(s): TAS5717 TAS5719 TAS5717 TAS5719 SLOS655A – NOVEMBER 2010 – REVISED FEBRUARY 2011 www.ti.com APPLICATION INFORMATION LINE DRIVER AMPLIFIERS Single-supply headphone and line driver amplifiers typically require dc-blocking capacitors. The top drawing in Figure 47 illustrates the conventional line driver amplifier connection to the load and output signal. DC blocking capacitors for headphone amps are often large in value, and a mute circuit is needed during power up to minimize click and pop for both headphone and line driver. The output capacitors and mute circuits consume PCB area and increase cost of assembly, and can reduce the fidelity of the audio output signal. Conventional Solution 9–12 V VDD + Mute Circuit Co + + OPAMP Output VDD/2 – GND MUTE TAS5717 Solution 3.3 V DirectPath VDD + Mute Circuit Output GND TAS5717 – VSS HP_SD S0445-01 Figure 47. Conventional and DirectPath HP and Line Driver The DirectPath™ amplifier architecture operates from a single supply but makes use of an internal charge pump to provide a negative voltage rail. Combining the user provided positive rail and the negative rail generated by the IC, the device operates in what is effectively a split supply mode. The output voltages are now centered at zero volts with the capability to swing to the positive rail or negative rail, combining this with the build in click and pop reduction circuit, the DirectPath™ amplifier requires no output dc blocking capacitors. The bottom block diagram and waveform of Figure 47 illustrate the ground-referenced headphone and line driver architecture. This is the architecture of the TAS5717/9. COMPONENT SELECTION Charge Pump The charge pump flying capacitor serves to transfer charge during the generation of the negative supply voltage. The PVSS capacitor must be at least equal to the charge pump capacitor in order to allow maximum charge transfer. Low ESR capacitors are an ideal selection, and a value of 1µF is typical. Capacitor values that are smaller than 1µF can not be recommended for the HP section as it will limit the negative voltage swing in low impedance loads.

A good low equivalent-series-resistance (ESR) ceramic capacitor, typically 1µF, placed as close as possible to the device PVDD leads works best. Placing this decoupling capacitor close to the TAS5717/9 is important for the performance of the amplifier. For filtering lower frequency noise signals, a 10µF or greater capacitor placed near the audio power amplifier would also help, but it is not required in most applications because of the high PSRR of this device. Gain Setting Resistors Ranges The gain setting resistors, Rin and Rfb, must be chosen so that noise, stability and input capacitor size of the TAS5717/9 is kept within acceptable limits. Voltage gain is defined as Rfb divided by Rin. Selecting values that are too low demands a large input ac-coupling capacitor, CIN. Selecting values that are too high increases the noise of the amplifier. Table 25 lists the recommended resistor values for different gain settings. Table 25.

Inverting Gain Configuration Input-Blocking Capacitors DC input-blocking capacitors are required to be added in series with the audio signal into the input pins of the TAS5717/9. These capacitors block the DC portion of the audio source and allow the TAS5717/9 inputs to be properly biased to provide maximum performance. The input blocking capacitors also limit the DC gain to 1, limiting the DC-offset voltage at the output. These capacitors form a high-pass filter with the input resistor, Rin. The cutoff frequency is calculated using Equation 1. For this calculation, the capacitance used is the input-blocking capacitor and the resistance is the input resistor chosen from Table 25, then the frequency and/or capacitance can be determined when one of the two values is given. 1 1 fc in = Cin = 2p ´ Rin ´ Cin 2p ´ fc in ´ Rin (1) Using the TAS5717/9 as a 2nd order filter Several audio DACs used today require an external low-pass filter to remove out of band noise. This is possible with the TAS5717/9 as it can be used like a standard OPAMP. Several filter topologies can be implemented both single ended and differential. In the figure below a Multi Feed Back (MFB), with differential input and single ended input is shown. An AC-coupling capacitor to remove dc-content from the source is shown, it serves to block any dc content from the source and lowers the dc-gain to 1 helping reducing the output dc-offset to minimum. 58 Submit Documentation Feedback © 2010–2011, Texas Instruments Incorporated Product Folder Link(s): TAS5717 TAS5719 TAS5717 TAS5719 SLOS655A – NOVEMBER 2010 – REVISED FEBRUARY 2011 www.ti.com The component values can be calculated with the help of the TI FilterPro™ program available on the TI website at: http://focus.ti.com/docs/toolsw/folders/print/filterpro.html Inverting Input R2 C3 R1 C1 R3 –In – C2 TAS5717 + S0447-01 Figure 49. Second-Order Active Low-Pass Filter The resistor values should have a low value for obtaining low noise, but should also have a high enough value to get a small size ac-coupling cap. C2 can be split in two with the midpoint connected to GND, this can increase the common-mode attenuation. Pop-Free Power Up Pop-free power up is ensured by keeping the HP_SD low during power supply ramp up and down. The pin should be kept low until the input AC-coupling capacitors are fully charged before asserting the HP_SD pin high, this way proper pre-charge of the ac-coupling is performed and pop-less power-up is achieved. Figure 50 illustrates the preferred sequence. Supply Supply Ramp HP_SD Time for AC-Coupling Capacitors to Charge T0463-01 Figure 50.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device.
