Evaluation board Rev.A for AK4562
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.
