AK4536
16-Bit Mono CODEC with ALC & MIC/SPK-AMP
GENERAL DESCRIPTION
The AK4536 is a 16-bit mono CODEC with Microphone-Amplifier and Speaker-Amplifier. Input circuits
include a Microphone-Amplifier and an ALC (Automatic Level Control) circuit. Output circuits include a
Speaker-Amplifier and Mono Line Output. The AK4536 suits a moving picture of Digital Still Camera and
etc. The AK4536 is housed in a space-saving 28-pin QFN package.
