AKD4552-A is an evaluation board for the digital audio 24bit A/D and D/A converter, AK4552. The AKD4552-A can evaluate A/D converter and 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 AKD4552-A has the interface with AKM’s ADC evaluation boards. Therefore, it’s easy to evaluate the D/A section. The AKD4552-A also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector.
