The AK4635 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 AK4635 suits a moving picture of Digital Still Camera and etc. This

speaker-Amplifier supports a Piezo Speaker. The AK4635 is housed in a space-saving 29-pin Wafer

Level CSP 2.5mm x 3.0mm package.
