GENERAL DESCRIPTION

The AK5358B is a stereo A/D Converter with a wide sampling rate range of 8kHz

∼ 96kHz and it is suitable

for consumer to professional audio system. The AK5358B achieves high accuracy and low cost by using

Enhanced dual bit

ΔΣ techniques. No external components are required with single-ended analog inputs.

The audio interface has two formats (MSB justified, I

DVR and AV Receiver.
