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.
