AK5380
96kHz 24Bit ADC with Input

The AK5380 is a stereo A/D Converter with wide sampling rate of 4kHz~96kHz and is suitable for Highend audio system. The AK5380 achieves high accuracy and low cost by using Enhanced dual bit 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.
