AK4480 Evaluation Board Rev.2
General Description
AKD4480-SB is an evaluation board, which is 32Bit ΔΣDAC. The AKD4480-SB includes a LPF which can
add differential analog outputs from the AK4480 and also has a digital interface. Therefore, it is easy to
evaluate sound quality of the AK4480.

„ Evaluation mode
1. DIR (COAX) (default)
The DIR generates MCLK, BICK, LRCK and SDATA from the received data through BNC connector (J7). It is
possible for the evaluation using such as CD test disk.
Setting: R87 = open;
R88 = short (0Ω)
COAX is recommended for an evaluation of the Sound quality.
2. DIR (Optical)
The DIR generates MCLK, BICK, LRCK and SDATA from the received data through Optical connector
(PORT2). It is possible for the evaluation using such as CD test disk.
Setting: R87 = short (0Ω);
R88 = open
3. All clocks are fed through the PORT1.
Setting: R54, R55, R56, R58 = open
R50, R51, R52 = 100Ω; R53 = 5.1Ω

External Analog Circuit
The differential output circuit and LPF is implemented on board. The differential outputs of AK4480 is buffered by
non-inverted circuit (2nd order LPF, fc=106.4k, Q=0.698, G=+3.9dB). LPF adds differential outputs (1st order LPF, fc=284k,
G=-0.84dB). LME49710NA 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.
