GENERAL DESCRIPTION
The AK4646EZ features a stereo CODEC with a built-in Microphone-Amplifier and Speaker-Amplifier.
Input circuits include a Microphone-Amplifier and an ALC (Auto Level Control) circuit, and Output circuits
include a Speaker-Amplifier. These circuits are suitable for portable application with recording/playback
function. The AK4646 is available in a 32pin QFN (4mm x 4mm 0.4mm pitch), utilizing less board space
than competitive offerings.
