AK5359
24-Bit 192kHz âΣ ADC
GENERAL DESCRIPTION
The AK5359 is a stereo A/D Converter with wide sampling rate of 8kHz â¼ 216kHz and is suitable for
consumer to professional audio system. The AK5359 achieves high accuracy and low cost by using
Enhanced dual bit âΣ techniques. The AK5359 requires no external components because the analog
inputs are single-ended. The audio interface has two formats (MSB justified, I2S) and can correspond to
various systems like DTV, DVR and AV Receiver.
