[AK4950] AK4950 24bit Stereo CODEC with MIC/SPK/Cap-less VIDEO-AMP & mini DSP GENERAL DESCRIPTION The AK4950 is a 24bit stereo CODEC with a microphone, speaker and headphone amplifiers. The input circuits include a microphone amplifier and the output circuits include a speaker amplifier. It is suitable for portable application with recording/playback function. The integrated charge pump generates an internal negative power supply rail and removes the output coupling capacitor. A one channel composite In/Out video amplifier is also integrated. Digital sound processing is provided by the internal DSP. The AK4950 is available in a small 32pin QFN (4mm x 4mm, 0.4mm pitch), saving more board space. FEATURES 1.
