AK5358AET AKM Semiconductor

AK5358A AK5358A 96kHz 24-Bit ADC GENERAL DESCRIPTION The AK5358A is a stereo A/D Converter with wide sampling rate of 8kHz 96kHz and is suitable for consumer to professional audio system. The AK5358A achieves high accuracy and low cost by using Enhanced dual bit techniques. The AK5358A requires no external components because the analog 2 inputs are single-ended. The audio interface has two formats (MSB justified, I S) and can correspond to various systems like DTV, DVR and AV Receiver.
