GENERAL DESCRIPTION
The AK4665A is a 20bit CODEC with built-in Input PGA and Headphone Amplifier. The AK4665A
includes a microphone/line input selector and an ALC circuit for input, and a stereo line output buffer,
analog volume controls and capless stereo headphone amplifier for output. The AK4665A also features
an analog mixing circuit that allows easy interfacing in mobile phone and portable communication
designs. The integrated headphone amplifier features “pop-free” power-on/off, a mute control and
delivers 31mW of power into 16
load. The AK4665A is housed in a 32pin QFN package, making it
suitable for portable applications.
