Overview
[AK4649VN] AK4649VN 24bit Stereo CODEC with MIC/SPK-AMP GENERAL DESCRIPTION The AK4649VN features a stereo CODEC with a built-in Microphone-Amplifier and Speaker-Amplifier.
Input circuits include a Microphone-Amplifier and an ALC (Automatic Level Control) circuit, and Output circuits include a Speaker-Amplifier.
These circuits are suitable for portable application with recording/playback function.
The AK4649VN is available in 32pin QFN(5x5mm 0.
5mm pitch) utilizing less board space than competitive offerings.
