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.
