3 Description
The TAS5731M is a 30-W, efficient, digital-audio
stereo power amplifier for driving stereo bridge-tied
speakers. One serial data input allows processing of
up to two discrete audio channels and seamless
integration to most digital audio processors and
MPEG decoders. The device accepts a wide range of
input data and data rates. A fully programmable data
path routes these channels to the internal speaker
drivers.
The TAS5731M is a slave-only device receiving all
clocks from external sources. The TAS5731M
operates with a PWM carrier between a 384-kHz
switching rate and a 352-kHz switching rate,
depending on the input sample rate. Oversampling
combined with a fourth-order noise shaper provides a
flat noise floor and excellent dynamic range from
20 Hz to 20 kHz.
