AK4634
16-Bit Mono CODEC with ALC & MIC/SPK -AMP
GENERAL DESCRIPTION
The AK4634 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 AK4634 is suitable for a moving picture of Digital Still
Camera and etc. This speaker-Amplifier supports a Piezo Speaker. The AK4634 is housed in a
space-saving 32-pin QFN 5mm x 5mm package and 29-pin CSP 2.5mm x 3mm package.
