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.

Note 5. This value is the full scale (0dB) of the input voltage. Input voltage is proportional to VA voltage.
Vin = 0.6 x VA (Vpp).
Note 6. PSR is applied to VA and VD with 1kHz, 50mVpp.
Note 7. All digital input pins are held VD or DGND.
