AK7735 Overview
Description
The AK7735 is a highly integrated digital signal processor, including a 24-bit stereo ADC with MIC gain amplifiers, a 24-bit stereo ADC with input selector, two 32-bit stereo DACs, 2 stereo sampling rate convertors supporting the sampling frequency up to 192kHz and dual DSPs for Audio/HF process. Each DSP has 3072step/fs (when fs=48kHz) parallel processing power.
