GENERAL DESCRIPTION

AKD4562 is an evaluation board for the portable digital audio 20bit A/D and D/A converter, AK4562. The

AKD4562 can evaluate A/D converter D/A converter separately in addition to loopback mode (A/D

→

D/A). The A/D section can be evaluated by interfacing with AKM’s DAC evaluation boards directly. The

AKD4562 has the interface with AKM’s wave generator using ROM data and AKM’s ADC evaluation

boards. Therefore, it’s easy to evaluate the D/A section. The AKD4562 also has the digital audio interface

and can achieve the interface with digital audio systems via opt-connector.
