AK5353 96kHz 24-BIT ADC

The AK5353 is a stereo A/D Converter with wide sampling rate of 4kHz∼96kHz and is suitable for multimedia audio system. The AK5353 achieves high accuracy and low cost by using Enhanced dual bit ∆Σ techniques. The AK5353 requires no external components because the analog inputs are single-ended. The audio interface has two formats (MSB justified, I2S) and can.
