2.AUDIO AMPLIFIER STAGES
A. MAIN AMPLIFIER (TAS5719)(6-8 W option)
a. General Description
The TAS5717/TAS5719 is a 10-W/15-W, efficient, digital audio-power amplifier for driving stereo
bridgetied 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 of
input data and data rates. A fully programmable data path routes these channels to the internal speaker
drivers.

drivers.
The TAS5717/9 is a slave-only device receiving all clocks from external sources. The
TAS5717/TAS5719 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.
