–
–
Soft Mute (50% Duty Cycle)  
Programmable Dynamic Range Control  
16 Adaptable Biquads for Speaker EQ  
The TAS5705 is a 20-W, efficient, digital audio power  
amplifier for driving stereo bridge-tied speakers. Two  
serial data inputs allow processing of up to four  
discrete audio channels and seamless integration to  
most digital audio processors and MPEG decoders.  
The device accepts a wide range of input data and  
clock rates. A fully programmable data path allows  
these channels to be routed to the internal speaker  
drivers or output via the line-level subwoofer or  
headphone PWM outputs.  
–
Seven Biquads for Left and Right  
Channels  
–
Two Biquads for Subwoofer Channel  
–
–
–
–
–
Adaptive Coefficients for DRC Filters  
Programmable Input and Output Mixers  
DC Blocking Filters  
Loudness Compensation for Subwoofer  
The TAS5705 is a slave-only device receiving clocks  
from external sources. The TAS5705 operates at a  
384-kHz switching rate for 32-, 48-, 96-,and 192-kHz  
data and 352.8-kHz switching rate for 44.1-, 88.2-  
and 176.4-kHz data. The 8× oversampling combined  
with the fourth-order noise shaper provides a flat  
noise floor and excellent dynamic range from 20 Hz  
to 20 kHz.  
Automatic Sample Rate Detection and  
Coefficient Banking for DRC and EQ
