GENERAL DESCRIPTION

The AK5384 is a 4-channel A/D Converter with wide sampling rate of 8kHz ~ 96kHz and is suitable for Multi-channel audio system. The AK5384 achieves high accuracy and low cost by using Enhanced dual bit DS techniques. The AK5384 supports master mode and TDM format. Therefore, the AK5384 is suitable for multi-channel audio system.
