AK5386

Single-ended 24-Bit 192kHz ∆Σ ADC

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.
