AK5353
96kHz 24Bit ∆Σ ADC with Single–ended Input
GENERAL DESCRIPTION
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 correspond to many systems like
Karaoke, surround.
