General Description

The AK7782 is an audio digital signal processor with integrated 24bit 5ch ADCs, an 8:2 stereo input selector and sample rate converters that support 2ch inputs and the frequency up to 96kHz.

The ADC supports wide range of sampling frequency from 7.35kHz to 96kHz.

Two integrated audio DSPs have high performance processing speed of 2560step/fs (at 48kHz sampling), and two 6k-word delay RAMs allow surround processing, time alignment adjusting and FIR filtering.
