AK4671

Stereo CODEC with MIC/RCV/HP-AMP

GENERAL DESCRIPTION

The AK4671 is a stereo CODEC with a built-in Microphone-Amplifier, Receiver-Amplifier and

Headphone-Amplifier. The AK4671 features dual PCM I/F in addition to audio I/F that allows easy

interfacing in mobile phone designs with Bluetooth I/F. The AK4671 is available in a 57pin BGA, utilizing

less board space than competitive offerings.
