STA304 Datasheet - STMicroelectronics

DESCRIPTION
The STA304 Digital Audio Processor is a single chip device implementing end to end digital solution for audio application. In conjunction with STA500 power bridge it gives the full digital DSP-to-power high quality chain with no need for audio Digital-to-Analog converters between DSP and power stage.
