[AK5358B]
AK5358B
96kHz 24-Bit ΔΣ ADC
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, I2S) and can correspond to various systems like DTV,
DVR and AV Receiver.
