[AK4953A] 24bit Stereo CODEC with MIC/HP/SPK-AMP GENERAL DESCRIPTION The AK4953A is a low power consumption 24bit stereo CODEC with a microphone, headphone and speaker amplifiers. The input circuits include a microphone amplifier and an ALC (Automatic Level Control) circuit, and the output circuits include a cap-less headphone amplifier and a speaker amplifier. It is suitable for portable application with recording/playback function. The integrated charge pump circuit generates a negative voltage and removes the output AC coupling capacitors. The speaker amplifier has a wide operating voltage range, which is from 0.9V to 5.5V, enabling a direct drive to batteries. The AK4953A is available in a small 36-pin QFN (5x5mm 0.4mm pitch), utilizing less board space than petitive offerings. Features 1.
