AK4633
16-Bit ∆Σ Mono CODEC with ALC & MIC/SPK-AMP
GENERAL DESCRIPTION
The AK4633 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 AK4633 suits a moving picture of Digital Still Camera and
etc. This speaker-Amplifier supports a Piezo Speaker. The AK4633 is housed in a space-saving 24-pin
QFN package.
