No Preview Available ! [AK4649] AK4649 24bit Stereo CODEC with MIC/SPK-AMP GENERAL DESCRIPTION The AK4649 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 AK4649 is available in a 29pin CSP (3x3.3mm 0.5mm pitch), utilizing less board space than competitive offerings. FEATURES 1.
