GENERAL DESCRIPTION

The AK5357 is a stereo A/D Converter with wide sampling rate of 4kHz ～ 96kHz and is suitable for multimedia audio system. The AK5357 achieves high accuracy and low cost by using Enhanced dual bit ΔΣ techniques. The AK5357 requires no external components because the analog inputs are single-ended. The audio interface has two formats (MSB justified, I2S) and can correspond to many systems like Karaoke, surround.
