Evaluation board Rev.0 AK4550
GENERAL DESCRIPTION AKD4550-E evaluation board portable digital audio 16bit converter, AK4550. AKD4550-E evaluate converter converter separately addition loopback mode (A/D D/A). section evaluated interfacing with AKM's evaluation boards directly. AKD4550 interface with AKM's evaluation boards. Therefore, it's easy evaluate section. AKD4550-E also digital audio interface achieve interface with digital audio systems opt-connector.
