DESCRIPTION
The TAS5717/TAS5719 is a 10-W/15-W, efficient,
digital audio-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 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.
