GENERAL DESCRIPTION

The AK5380 is a stereo A/D Converter with wide sampling rate of 4kHz~96kHz and is suitable for High-end audio system. The AK5380 achieves high accuracy and low cost by using Enhanced dual bit ΔΣ techniques. The AK5380 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 music instrument and AV receiver.
