AK4633 Datasheet | Asahi Kasei Microdevices

DESCRIPTION The AK4633 is a 16-bit mono CODEC with Microphone-Amplifier and Speaker-Amplifier. Input circuits include a Microphone-Amplifier and an ALC (Automatic Level Control) circuit. Output circuits include a Speaker-Amplifier and Mono Line Output. The AK4633 suits a moving picture of Digital Still Camera and etc. This speaker-Amplifier supports a Piezo Speaker. The AK4633 is housed in a space-saving 24-pin QFN package. FEATURE 1. 16-Bit Delta-Sigma Mono CODEC 2.
