GENERAL DESCRIPTION

AKD4633-A is an evaluation board for the AK4633VN, 16bit mono CODEC with MIC/SPK amplifier. The
AKD4633-A can evaluate A/D converter and D/A converter separately in addition to loopback mode (A/D

D/A). AKD4633-A also has the digital audio interface and can achieve the interface with digital audio

systems via opt-connector.
