GENERAL DESCRIPTION
The AK4648 is a stereo CODEC with a built-in Microphone-Amplifier, Headphone-Amplifier, and
Speaker-Amplifier. The AK4648 features analog mixing circuits and PLL that allows easy interfacing in
mobile phone and portable A/V player designs. The AK4648 is available in a CSP (3.7mm x 3.8mm),
utilizing less board space than competitive offerings.
