Description

The AK5353 is a stereo A/D Converter with a wide sampling rate of 4kHz∼96kHz. It is suitable for multimedia audio systems and 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 be used in many systems such as Karaoke and surround sound.
