DESCRIPTION
Audio/PWM Processing
The TAS5701 is a 20-W efficient, digital audio power
BD (Filter-free) Modulation Supporting
amplifier for driving stereo bridge-tied speakers. Two
Bridge-Tied Loads ONLY
serial data inputs support up to 3 discrete audio
channels. The SDIN1 input is routed to the internal
4-Step Volume Control (0 dB, 6 dB, 12 dB,
left and right outputs. The SDIN2 input is dedicated to
18 dB)
the SUB_PWM± outputs.
– All Channels Share Same Control
The TAS5701 is a clock slave-only device receiving
Soft Mute (50% Duty Cycle)
clocks from external sources. The TAS5701 operates
DC Blocking Filters
at a 384-kHz switching rate for 32-, 48-, 96-, and
Fixed Maximum Modulation Limit At 97.7%
