Evaluation board Rev.C for AK4394
General Description
The AKD4394 is an evaluation board for AK4394, which is 192kHz sampling 24Bit ∆Σ DAC. The AKD4394
includes a LPF which can add differential analog outputs from the AK4394 and also has a digital interface with
AKM’s wave generator using ROM data and AKM’s ADC evaluation boards. Therefore, it is easy to evaluate the
AK4394.
