Operation sequence
(1) Set up the power supply lines.
[+12V]
(orange jack) = +12 ∼ +15V
[-12V]
(blue jack)
= -12 ∼ -15V
[AGND] (black jack)
= 0V
[DGND] (black jack)
= 0V
Each supply line should be distributed from the power supply unit.
±12V are supplied to analog interface.
+12V is regulated to +5V and +3.3V by regulators(T1,T2).
+5V is supplied to digital interface, AK4626A and TVDD of AK4112B.
+3.3V is supplied to AVDD and DVDD of AK4112B and TVDD of AK4626A.
(2) Set up the evaluation mode and jumper pins. (See p.6.)
(3) Power on.
The AK4626A, AK4112B and AK4103A should be reset once bringing PDN(SW1) “L” upon power-up.
(4) Set up software.
The control mode of AK4626A and AK4112B is fixed to “serial”.

Gain of analog input circuit is

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
103.6dB (measurement).
Therefore total S/N of op-amp circuit and ADC is
103.59dB (measurement: 103.6dB).

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 out-of-band
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
105.94dB (measurement: 106.1dB).
