GENERAL DESCRIPTION
The AK4651 targeted at PDA and other low-power, small size applications. It features a 16bit stereo
CODEC with a built-in Microphone-Amplifier, Headphone-Amplifier and Speaker-Amplifier. Input circuits
include a Microphone-Amplifier and an ALC (Auto Level Control) circuit. The AK4651 is connected with
AC’97 controller (CPU) via AC-Link. The AK4651 is available in a very small 57pin BGA, utilizing less
board space than competitive offerings.
