[AK5380]
AK5380
96kHz 24Bit DS ADC with Single–ended Input
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 DS
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.
