AKD4385-SC
AK4385 Evaluation board Rev.1
General Description
The AKD4385-SC is an evaluation board for AK4385, which is 192kHz sampling 24Bit ∆Σ DAC. The
AKD4385-SC includes a LPF which can add differential analog outputs from the AK4385 and also has a digital
interface. Therefore, it is easy to evaluate the AK4385.

„ Evaluation mode
1. DIR (COAX) (default)
It is possible to evaluate the AK4385 by using CD disk. The DIR generates MCLK, BICK, LRCK and SDATA from the
received data through BNC connector (J1). Setting of jumper is shown below.

External Analog Filter Circuit
The 2nd order LPF (fc=93.2kHz, Q=0.712) which adds differential outputs of the AK4385 is implemented on the board. When
the further attenuation of the out-of-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 AK4382A is [email protected]
