AK4632
AK4632 is 16-Bit Mono CODEC manufactured by Asahi Kasei Microdevices.
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. FEATURE
