AKD4388-SB
AK4388 Evaluation board Rev.1
General Description
The AKD4388-SB is an evaluation board for AK4388, which is 192kHz sampling 24Bit ∆Σ 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.

Table 1. Set up of power supply lines
Each supply line should be distributed from the power supply unit.
2) Set-up the jumper pins
3) Set-up the DIP switches. (See the followings.)
4) Power on
The AK4388 should be reset once by bringing SW4 (PDN) “L” upon power-up.

„ 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.

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.
