AK4397 Evaluation board
General Description
The AKD4397-SB is an evaluation board for AK4397, which is 192kHz sampling 32Bit ΔΣ DAC. The
AKD4397-SB includes a LPF which can add differential analog outputs from the AK4397 and also has a
digital interface. Therefore, it is easy to evaluate sound quality of the AK4397.

DIR(COAX) (default)
J1 is used for the evaluation using such as CD test disk. The DIR generates MCLK, BICK and LRCK SDATA from the
received data through BNC connector (J1). Setting of jumper is shown below.

External Analog Circuit
nd
The differential output circuit and LPF is implemented on board. The differential outputs of AK4397 is buffered by non-inverted circuit(2
st
order LPF, fc=182k, Q=0.637, G=+3.9dB). LPF adds differential outputs(1 order LPF, fc=284k, G=-0.84dB). NJM5534D is used for
op-amp on this board that has low noise and high voltage torelance characteristics. Analog signal is output via BNC connectors on the board.
The output level is about 2.8Vrms ([email protected]=5.0V) by BNC.
