GENERAL DESCRIPTION 

The AKD4953A-B is an evaluation board for the AK4953A 24bit CODEC with built-in PLL and MIC/HP/SPK 
Amplifier. The AKD4953A-B has the interface with AKM’s A/D evaluation boards. Therefore, it’s easy to 
evaluate the AK4953A. The AKD4953A-B also has the digital audio interface and can achieve the interface 
with digital audio systems via opt-connector.
