AK4632
16-Bit ∆Σ Mono CODEC with ALC & MIC/SPK/Video-AMP
GENERAL DESCRIPTION
The AK4632 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 AK4632 suits a moving picture of Digital Still Camera and etc. This
speaker-Amplifier supports a Piezo Speaker. The AK4632 is housed in a space-saving 32-pin QFN
package.

The audio function of the AK4632 is compatible with that of the AK4631. Since the register map of audio
function is the same as the AK4631’s, the software of the audio function can run on the ak4632 without any
change.
