Product Summary
The TAS5709PHPR is a 20-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 TAS5709PHPR accepts a wide range of input data and data rates. A fully programmable data path routes these channels to the internal speaker drivers. The TAS5709PHPR is a slave-only device receiving all clocks from external sources.
