Description

The AK4954AEN is a low power consumption 32-bit stereo CODEC with a microphone, a headphone and a 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 AK4954AEN is available in a small 32-pin QFN (4mm x 4mm, 0.4mm pitch), utilizing less board space than competitive offerings.
