GENERAL DESCRIPTION
The AK4563A is low power operation, 16bit CODEC that include 4ch ADC and 2ch DAC. The AK4563A
also includes ALC (Automatic Level Control) circuit, therefore is suitable for microphone application and
etc. As the ALC circuit can be stopped by controlling
P, IPGA can also be used as the manual volume.
Digital I/F can be input/output from 1.5V to 3.0V by external power supply. The AK4563A can be
powered-down by each block, therefore the AK4563A is suitable to low power dissipation in system.
