DESCRIPTION
The true digital audio amplifier (TDAA) is a new
paradigm in digital audio. One TDAA system consists of
the TAS5001 PCM-PWM modulator device + TAS5100
PWM power output device. This system accepts a serial
PCM digital audio stream and converts it to a 3.3-V
PWM audio stream (TAS5001). The TAS5100 device
then provides a large-signal PWM output. This digital
PWM signal is then demodulated providing power
output for driving loudspeakers. This patented
technology provides low-cost, high-quality, highefficiency digital audio applicable to many audio
systems developed for the digital age. The TAS5001 is
an innovative, cost-effective, high-performance 24-bit
stereo PCM-PWM modulator based on Equibit
technology. It has a wide variety of serial input options
including right-justified (16, 20, or 24 bits), IIS (16, 20,
or 24 bits), left-justified (16 bits), or DSP (16 bits) data
formats. It is fully compatible with AES standard
sampling rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz,
and 96 kHz. The TAS5001 also provides a de-emphasis
function for 44.1-kHz and 48-kHz sampling rates.

functional description
serial audio port
The serial audio port consists of a shift clock (SCLK pin), a left/right frame synchronization clock (LRCLK pin),
and a data input (SDIN pin). The serial audio port supports standard serial PCM formats (Fs = 32-kHz, 44.1-kHz,
48-kHz, 88.2-kHz, 96-kHz stereo). See the serial interface formats section for more information.
system clocks—master mode and slave mode
The TAS5001 allows multiple system clocking schemes. Master mode indicates that the TAS5001 provides
system clocks to other parts of the system (M_S=1). Audio system clocks of frequency 256 Fs MCLK_OUT,
64 Fs SCLK, and Fs LRCLK are output from this device when it is configured in master mode. Slave mode
indicates that a system master other than the TAS5001 provides system clocks (LRCLK, SCLK, and MCLK_IN)
to the TAS5001 (M_S = 0). The TAS5001 operates with LRCLK and SCLK synchronized to MCLK. TAS5001
does not require any specific phase relationship between LRCLK and MCLK, but there must be synchronization.
In the slave mode MCLK_OUT is driven low. Table 1 shows all the possible master and slave modes.
oscillator/sampling frequency
The sampling frequency is determined by the crystal (master mode) or master clock in (slave mode) which
should be either 8.192 MHz (Fs = 32 kHz), 11.2896 MHz (Fs = 44.1 kHz), or 12.288 MHz (Fs = 48 kHz). Twice
the normal sampling frequency can be selected by using the DBSPD pin which allows usage of Fs = 88.2 kHz
or Fs = 96 kHz. In the double-speed slave mode (DBSPD = 1, M_S = 0), the external clock input is either
22.5796 MHz (Fs = 88.2 kHz) or 24.576 MHz (Fs = 96 kHz). Note that 32-kHz sampling is supported in the
normal speed modes. Table 1 explains the proper clock selection.

phase-locked loop (PLL)/clock generation
A low-jitter PLL is incorporated for internal use. Connections for the PLL external loop filter are provided as
PLL_FLT_RET and PLL_FLT_OUT. If the PLL loses lock, the PWM output status pins (VALID_L and VALID_R)
go low. Note that VALID_L and VALID_R can go low for other conditions as well. See the error status reporting
section for more information.

digital interpolation filter
The 24-bit high-performance linear phase FIR interpolation filter up-samples the input digital data at a rate of
four times (double speed mode = 88.2 kHz or 96 kHz), or eight times (normal mode = 32 kHz, 44.1 kHz, or 48
kHz) the incoming sample rate. This filter provides very low pass-band ripple and optimized time domain
transient response for accurate music reproduction.
digital PWM modulator
The interpolation filter output is sent to the modulator. This modulator consists of a high performance fourth order
digital noise shaper and a PCM-to-PWM converter. Following the noise shaper, the PCM signal is fed into a very
low distortion PCM-to-PWM conversion block, buffered, and output from the chip. The modulation scheme is
based on a 2-state control of the H-bridge output.
control, status, and operational modes
The TAS5001 control section consists of several control-input pins. Three serial mode pins (MOD0, MOD1, and
MOD2) are provided to select various serial data formats. During normal operating conditions if any of the
MOD0, MOD1, or MOD2 pins changes state, a reset sequence is initiated. Also provided are separate
power-down (PDN), reset (RESET), and mute (MUTE) pins.
power up
At power up the VALID_L and VALID_R pins are asserted low and the PWM outputs go to the hard mute state
in which the P outputs are held low and the M outputs are held high. Following initialization, the TAS5001 comes
up in the operational state (differential PWM audio). There are two cases of power-up timing. The first case is
shown in Figure 1 with RESET preceding PDN. The second case is shown in Figure 2 with PDN preceding
RESET.

reset
The reset signal for the TAS5001 must be applied whenever toggling the M_S, DBSPD signal. This reset is
asynchronous. See Figure 3 for reset timing. To initiate the reset sequence the RESET pin is asserted low. As
long as the pin is held low the chip is in the reset state. During this reset time the PWM outputs are hard-muted
(P-outputs held low and M-outputs held high) and the PWM outputs valid pins (VALID_L. VALID_R) are held
low. Assuming PDN is high, the rising edge of the reset pulse begins chip initialization. After the initialization
time, the TAS5001 begins normal operation.

power down
When PDN is low (see Figure 4), both the PLL and the oscillator are shut down. Note that power down is an
asynchronous operation. To place the device in total power-down mode, both RESET and PDN must be held
low. As long as these pins are held low, the chip is in the power-down state and the PWM outputs are hard muted
with the P outputs held low and the M outputs held high. To place the device back into normal mode, see the
power up section.
NOTE:In order for the dynamic logic to be properly powered down, the clocks should not be stopped
before the PDN pin goes low. Otherwise, the device may drain additional supply current.

mute
The TAS5001 provides a mute function that is used when the MUTE pin is asserted low. See Table 2 for mute
description. This mute is a quiet mute; that is, the mute is accomplished by outputting a zero value waveform
in which both sides of the differential PWM outputs have a 50% duty cycle (see Figure 5 for mute timing).

double speed
Double-speed mode is used to support sampling rates of 88.2 kHz and 96 kHz. In order to put the TAS5001 in
double-speed mode with the device in normal operating conditions, the RESET pin must be held low while
switching the DBSPD pin high. After the RESET pin is brought high again, a reset sequence takes place. If the
change is at power up, a power-up sequence is originated.
de-emphasis filter
Response – dB
For audio sources that have been preemphasized, a precision 50-µs/15-µs de-emphasis filter is provided to
support the sampling rates of 44.1 kHz and 48 kHz. Pins DEM_SEL and DEM_EN select the de-emphasis
functions. See Figure 6 for a graph showing the de-emphasis filtering characteristics. See Table 3 for
de-emphasis selection.

error status reporting (VALID_L and VALID_R)
The following is a list of the error conditions that will cause the VALID_L and VALID_R pins to be asserted low:
D No clocks
D Clock phase errors
When either of the above conditions is met, the VALID_L and VALID_R goes low and the PWM outputs go to
the hard mute state. If the error condition is removed, the TAS5001 is reinitialized and the VALID_L and VALID_R
pins are asserted high.
serial interface formats
The TAS5001 is compatible with eight different serial interfaces. Available interface options are IIS, right
justified, left justified, and DSP frame. Table 4 indicates how these options are selected using the MOD0, MOD1,

PWM outputs
Designed to be used with the TAS5100 family of H-Bridges, the PWM outputs provide differential 3.3-V
square-wave signals. During normal operation these outputs represent the input PCM audio in the pulse-width
modulation scheme. In the hard-mute state the P outputs (PWM_AP_L and PWM_AP_R) are held low and the
M outputs (PWM_AM_L and PWM_AM_R) are held high. In the quiet-mute state the differential PWM outputs
have a 50% duty cycle.

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)
