AK5357
24Bit 96kHz ∆Σ ADC
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.
