AK4686 Overview
The AK4686 is a single chip audio CODEC that includes one stereo ADC and two stereo DACs in addition to the input selector and the line drivers. The interfaces of ADC/DAC can accept up to 24bit input data and support asynchronous operation. Both the input stereo selector and output drivers support ground reference I/O to remove AC-coupling capacitors and reducing external parts.
