1) Gain
Gain of analog input circuit is
330/(330+330) = -6.02dB.
Therefore input level for this board is
+0.51dBV(=3.0Vpp)+6.02dB
= +6.53dBV = 6.00Vpp = 2.12Vrms.
2) S/N of op-amp circuit (Theory: BW=20k+A)
Non-inverting amp is implemented on board. The output noise level of op-amp circuit is
-126.01dBV = -132.54dB (0dB=+6.53dBV).
S/N of ADC is
101.6dB (measurement).
Therefore total S/N of op-amp circuit and ADC is
101.60dB (measurement: 101.6dB)

2) Gain, S/N and frequency response of op-amp circuit
1st-order filter with non-inverting amp is implemented on board to double the analog output level and attenuate
outband noise.
a) Gain
The gain is
1+4.7k/4.7k = +6.02dB.
Therefore the output level of this board is
0.51dBV(=3.0Vpp) + 6.02dB
= 6.53dBV = 6.00Vpp = 2.12Vrms.
b) S/N (Theory: BW=20k+A)
The output noise level of non-inverting amp
-110.36dBV = -116.89dB (0dB=6.53dBV)
S/N of DAC is
106.3dB (measurement)
Therefore total S/N of op-amp circuit and DAC is
105.90dB (measurement: 105.8dB).

The AK4586 can be controlled via the printer port (parallel port) of
IBM-AT compatible PC. Connect PORT1(uP-I/F) with PC by 10-line
flat cable packed with the AKD4586.
Take care of the direction of connector. There is a mark at pin#1.

(2) Evaluation of ADC
PORT2(TOTX176) is used for digital output. AK4103(DIT) generates audio bi-phase signal from received data
and which is output through optical connector (TOTX176). It is possible to connect AKM’s D/A converter
evaluation boards or the digital-amplifier which equips DIR input. SW2 is used to set the interface format and
clock mode of AK4103 (see DIP-SW set-up). Clock operation mode of the AK4586 should be set to X’tal mode
by the control software packed with the AKD4586. Clock operation mode is set by CM1-0 bit of Addr=02H.
(3) Evaluation of DAC<default>
PORT2(TORX176) or J10(BNC(RX)) is used for digital input. DIR of AK4586 generates MCLK, BICK, LRCK
and SDATA from the received data through optical connector(TORX176) or BNC connector. Used for the
evaluation using CD test disk. In case of using BNC connector, set JP2(RX) to “BNC” side. Nothing should be
connected to PORT4(AC3).
(4) Evaluation using AC3 decoder
Connect the AC3 decoder with PORT4(AC3). Decoded serial data is sent to AKD4586. JP26(SDTI1),
JP27(SDTI2) and JP27(SDTI3) should be open.
Clock operation mode set-up
Clock operation mode should be set as Table 2 at evaluation modes (1), (2) and (3). Both clock operation mode can
be used at other evaluation modes. Clock operation mode can be set by CM1-0 bits(Addr=02H) of AK4586. CM1-0
bits can be set by the software packed with AKD4586. Please refer to the datasheet of AK4586 for details.
