AK4647
Stereo CODEC with MIC/HP-AMP
GENERAL DESCRIPTION
The AK4647 features a s tereo CODEC with a built-in Microphone-Amplifier and Headphone-Amplifier.
Built-in PLL circuit supports an easy interface with variable systems. The AK4647 is available in a 48pin
LQFP, utilizing less board space than competitive offerings.
