AK4636
16-Bit Mono CODEC with ALC & MIC/SPK/Video-AMP
GENERAL DESCRIPTION
The AK4636 is a 16-bit mono CODEC with Microphone-Amplifier, Speaker-Amplifier and Video-
Amplifier. Input circuits include a Microphone-Amplifier and an ALC (Automatic Level Control) circuit.
Output circuits include a Speaker-Amplifier and Mono Line Output. Video circuits include a LPF and
Video-Amplifier. The AK4636 suits a video recording/playback system of Digital Still Cameras. The
AK4636 is housed in a space-saving 29-pin CSP 2.5mm x 3.0mm package (AK4636ECB) or a 32pin QFN
4.0mm x 4.0mm package (AK4636EN).
