The STA304A 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.
