1.0 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 qual-
ity chain with no need for audio Digital-to-Analog con-
verters between DSP and power stage.
