The device has differential inputs and uses external gain-setting resistors to support a gain range of ±1 V/V to ±10 V/V, and gain can be configured individually for each channel. Line outputs have ±8-kV IEC ESD protection, requiring just a simple resistor-capacitor ESD protection circuit. The DRV632 has built-in active-mute control for pop-free audio on/off control. The DRV632 has an external undervoltage detector that mutes the output when the power supply is removed, ensuring a pop-free shutdown. Using the DRV632 in audio products can reduce component count considerably compared to traditional methods of generating a 2-VRMS output. The DRV632 does not require a power supply greater than 3.3 V to generate its 5.6-Vpp output, nor does it require a split-rail power supply. The DRV632 integrates its own charge pump to generate a negative supply rail that provides a clean, pop-free ground-biased 2-VRMS output. The DRV632 is available in a 14-pin TSSOP. 1 2 3 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.

The top drawing in Figure 6 illustrates the conventional line-driver amplifier connection to the load and output signal. DC blocking capacitors are often large in value. The line load (typical resistive values of 600 Ω to 10 kΩ) combines with the dc blocking capacitors to form a high-pass filter. Equation 1 shows the relationship between the load impedance (RL), the capacitor (CO), and the cutoff frequency (fC). 1 fc = 2p R L CO (1) CO can be determined using Equation 2, where the load impedance and the cutoff frequency are known. 1 CO = 2p R L f c (2) If fC is low, the capacitor must then have a large value because the load resistance is small. Large capacitance values require large package sizes. Large package sizes consume PCB area, stand high above the PCB, increase cost of assembly, and can reduce the fidelity of the audio output signal. 9 V–12 V Conventional Solution VDD + + OPAMP Mute Circuit Co + Output VDD/2 – GND Enable 3.3 V DirectPath DRV632 Solution VDD Mute Circuit + DRV632 Output GND – VSS Enable Figure 6. Conventional and DirectPath Line Drivers 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 built-in click and pop reduction circuit, the DirectPath amplifier requires no output dc blocking capacitors. The bottom block diagram and waveform of Figure 6 illustrate the ground-referenced line-driver architecture. This is the architecture of the DRV632. 8 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Link(s): DRV632 DRV632 www.ti.com SLOS681 – JANUARY 2011 CHARGE-PUMP FLYING CAPACITOR AND PVSS CAPACITOR 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 1 mF is typical. Capacitor values that are smaller than 1 mF can be used, but the maximum output voltage may be reduced and the device may not operate to specifications. If the DRV632 is used in highly noise-sensitive circuits, it is recommended to add a small LC filter on the VDD connection. DECOUPLING CAPACITORS The DRV632 is a DirectPath line-driver amplifier that requires adequate power supply decoupling to ensure that the noise and total harmonic distortion (THD) are low. A good, low equivalent-series-resistance (ESR) ceramic capacitor, typically 1 mF, placed as close as possible to the device VDD lead works best. Placing this decoupling capacitor close to the DRV632 is important for the performance of the amplifier. For filtering lower-frequency noise signals, a 10-mF 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 RESISTOR RANGES The gain-setting resistors, RIN and Rfb, must be chosen so that noise, stability, and input capacitor size of the DRV632 are 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 1 lists the recommended resistor values for different inverting-input gain settings. Table 1. Recommended Resistor Values GAIN INPUT RESISTOR VALUE, RIN FEEDBACK RESISTOR VALUE, Rfb –1 V/V 10 kΩ 10 kΩ –1.5 V/V 8.2 kΩ 12 kΩ –2 V/V 15 kΩ 30 kΩ –10 V/V 4.7 kΩ 47 kΩ USING THE DRV632 AS A SECOND-ORDER FILTER Several audio DACs used today require an external low-pass filter to remove out-of-band noise. This is possible with the DRV632, as it can be used like a standard operational amplifier. Several filter topologies can be implemented, both single-ended and differential. In Figure 7, multi-feedback (MFB) with differential input and single-ended input are 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 to reduce the output dc offset to a minimum. The component values can be calculated with the help of the TI FilterPro™ program available on the TI Web site at: http://focus.ti.com/docs/toolsw/folders/print/filterpro.html.

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 capacitor. With the proposed values of R1 = 15 kΩ, R2 = 30 kΩ, and R3 = 43 kΩ, a dynamic range (DYR) of 106 dB can be achieved with a 1-mF input ac-coupling capacitor. INPUT-BLOCKING CAPACITORS DC input-blocking capacitors are required to be added in series with the audio signal into the input pins of the DRV632. These capacitors block the dc portion of the audio source and allow the DRV632 inputs to be properly biased to provide maximum performance. These capacitors form a high-pass filter with the input resistor, RIN. The cutoff frequency is calculated using Equation 3. For this calculation, the capacitance used is the input-blocking capacitor, and the resistance is the input resistor chosen from Table 1; then the frequency and/or capacitance can be determined when one of the two values is given. It is recommended to use electrolytic capacitors or high-voltage-rated capacitors as input blocking capacitors to ensure minimal variation in capacitance with input voltages. Such variation in capacitance with input voltages is commonly seen in ceramic capacitors and can increase low-frequency audio distortion. fcIN = 1 2p R INCIN or CIN = 1 2p fcIN R IN (3) DRV632 UVP OPERATION The shutdown threshold at the UVP pin is 1.25 V. The customer must use a resistor divider to obtain the shutdown threshold and hysteresis desired for a particular application. The customer-selected thresholds can be determined as follows: EXTERNAL UNDERVOLTAGE DETECTION External undervoltage detection can be used to mute/shut down the DRV632 before an input device can generate a pop. The shutdown threshold at the UVP pin is 1.25 V. The user selects a resistor divider to obtain the shutdown threshold and hysteresis for the specific application. The thresholds can be determined as follows: VUVP = (1.25 – 6 mA × R3) × (R1 + R2) / R2 Hysteresis = 5 mA × R3 × (R1 + R2) / R2 For example, to obtain VUVP = 3.8 V and 1-V hysteresis, we can use R1 = 3 kΩ, R2 = 1 kΩ, and R3 = 50 kΩ. 10 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Link(s): DRV632 DRV632 www.ti.com SLOS681 – JANUARY 2011 VSUP_MO R1 R3 UVP R2 LAYOUT RECOMMENDATIONS A proposed layout for the DRV632 can be seen in the DRV632EVM User's Guide, and the Gerber files can be downloaded from http://www.ti.com.
