GENERAL DESCRIPTION

The AK5386 is a stereo A/D Converter with wide sampling rate of 8kHz ～ 216kHz and is suitable for consumer to professional audio system. The AK5386 achieves high accuracy and low cost by using Enhanced dual bit ?Σ techniques. The AK5386 requires no external components because the analog inputs are single-ended. The audio interface has two formats (MSB justified, I2S) and can correspond to various systems like DVD Recorder, AV Receiver, PC Sound card and Music Instrument recording.
