AKD5374-A
Evaluation board Rev.2 for AK5374
GENERAL DESCRIPTION
AKD5374-A is an evaluation board for AK5374, which is a stereo A/D Converter with a USB 2.0 interface.
The AK5374 can be tested easily on the AKD5374-A, as the operation of the device is compatible with
USB standard audio class. The AKD5374-A has not only an external audio interface, but also an external
EEP-ROM that all descriptor contents are stored and customizable.
