DESCRIPTION  
Audio/PWM Processing  
The TAS5701 is a 20-W efficient, digital audio power  
amplifier for driving stereo bridge-tied speakers. Two  
serial data inputs support up to 3 discrete audio  
channels. The SDIN1 input is routed to the internal  
left and right outputs. The SDIN2 input is dedicated to  
the SUB_PWM± outputs.  
BD (Filter-free) Modulation Supporting  
Bridge-Tied Loads ONLY  
4-Step Volume Control (0 dB, 6 dB, 12 dB,  
18 dB)  
– All Channels Share Same Control  
The TAS5701 is a clock slave-only device receiving  
clocks from external sources. The TAS5701 operates  
at a 384-kHz switching rate for 32-, 48-, 96-, and  
192-kHz data and 352.8-kHz switching rate  
Soft Mute (50% Duty Cycle)  
DC Blocking Filters  
Fixed Maximum Modulation Limit At 97.7%  
44.1-,88.2-,  
and  
176.4-kHz  
data.  
The  
8×  
100-dB SNR – Measured at Maximum  
Output With THD+N = 1%, 1 kHz,  
A-Weighted Noise, Gain = 0 dB  
oversampling combined with the fourth-order noise  
shaper provides a flat noise floor and excellent  
dynamic range from 20 Hz to 20 kHz.  
THD < 0.1% at 1/2 Rated Power
