The AK4646 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, utilizing less board space than competitive offerings.
