[AK5358A]
AK5358A
96kHz 24-Bit ΔΣ 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 ΔΣ techniques. The AK5358A 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.
