AK4565  
Low Power 20bit CODEC with built-in ALC  
GENERAL DESCRIPTION  
The AK4565 is a low power voltage, 20bit CODEC. The recording feature includes four stereo inputs  
selector which switches among microphone and line inputs etc. And the input PGA has an ALC function,  
making it suitable for microphone application. The AK4565 has a dedicated power supply pin for digital  
I/F, which can support I/O level down to 1.5V. The AK4565 can be powered-down partly and is suitable  
for portable application.
