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, I2S) and can correspond to various systems like DTV, DVR and AV Receiver.
