AK5357

ASAHI KASEI [AK5357] www.DataSheet4U.com 24Bit 96kHz ∆Σ ADC AK5357 GENERAL DESCRIPTION The AK5357 is a stereo A/D Converter with wide sampling rate of 4kHz ∼ 96kHz and is suitable for multimedia audio system. The AK5357 achieves high accuracy and low cost by using Enhanced dual bit ∆Σ techniques. The AK5357 requires no external components because the analog inputs are single-ended. The audio interface has two formats (MSB justified, I2S) and can correspond to many systems like Karaoke, surround.
