SUB WOOFER MAIN AMPLIFIER (TAS5727)

Description
The TAS5727 is a 25-W, efficient, digital-audio power amplifier for driving stereo bridge-tied
speakers.One serial data input allows processing of up to two discrete 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 TAS5727 is a slave-only device receiving all clocks from external sources. The TAS5727 operates
with a PWM carrier between a 384-kHz switching rate amd a 288-kHz switching rate, depending on the input
sample rate. Oversampling combined with a fourth-order noise shaper provides a flat noise flor and excellent
dynamic range from 20 Hz to 20 Khz.
