AK7746 Description

The AK7746 is a highly integrated audio processor, including 5 A/D channels, an input mux that can select 2 stereo pairs from 8 stereo inputs, and an on-chip DSP. High quality analog performance is provided by the ADC’s achieving 98dB (48kHz) dynamic range. The A/D supports sampling frequencies from 8kHz to 96kHz.
