DIGITAL AUDIO and MULTIMEDIA SOUND CODECs
AK4636
16-Bit Mono CODEC with ALC & MIC/SPK/Video-AMP
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 3.0mm package (AK4636ECB) or a 32pin QFN 4.0mm 4.0mm package (AK4636EN).
