GENERAL DESCRIPTION
The AK5358 is a stereo A/D Converter with wide sampling rate of 8kHz
∼
96kHz and is suitable for
consumer to professional audio system. The AK5358 achieves high accuracy and low cost by using
Enhanced dual bit
∆Σ
techniques. The AK5358 requires no external components because the analog
inputs are single-ended. The audio interface has two formats (MSB justified, I
2
S) and can correspond to
various systems like DTV, DVR and AV Receiver.
