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.
