AK4388 Evaluation board Rev.1
General Description The AKD4388-SB is an evaluation board for AK4388, which is 192kHz sampling 24Bit DAC. The AKD4388-SB includes a LPF which can add differential analog outputs from the AK4388 and also has a digital interface. Therefore, it is easy to evaluate the AK4388.

Evaluation mode
1. DIR (COAX) (default) It is possible to evaluate the AK4388 by using CD disk. The DIR generates MCLK, BICK, LRCK and SDATA from the received data through RCA connector (J3). Setting of jumper is shown below. COAX is recommended for an evaluation of the Sound quality.

External Analog Circuit
The 2nd order LPF (fc=125.6kHz, Q=0.753) which adds differential outputs of the AK4388 is implemented on the board. When the further attenuation of the out-band noise is needed, some additional LPF is required. Analog signal is output through BNC connectors on the board. And the output level of the AK4388 is 5.67Vpp@5V.
