2) Gain and S/N of op-amp circuit

Two stages of inverting op-amp circuit are implemented on board to convert single-ended input to full-differential
input for ADC of AK4527B.

a) Gain

The gain of each op-amp circuit is as following table:

Gain[dB]

First step

-12.40

Second step

0.00

Therefore input level for this board is

-5.51dBV(=1.5Vpp)+12.40dB

= +6.89dBV = 6.25Vpp = 2.21Vrms.

b) S/N (Theory: BW=20k+A)

The output noise level of each op-amp circuit is as following table:

Noise[dBV]

First step

-120.56

Second step

-115.91

The noise level summing differential output of op-amp circuit is

-113.64dBV = -114.13dB (0dB = +0.49dBV = 3Vpp).

S/N of ADC is

104.5dB (measurement).

Therefore total S/N of op-amp circuit and ADC is

104.05dB (measurement: 103.9dB).

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 = +6.00dB.

Therefore the output level of this board is
0.51dBV(=3.0Vpp) + 6.00dB
= 6.51dBV = 6.0Vpp = 2.12Vrms.

b) S/N (Theory: BW=20k+A)

The output noise level of non-inverting amp
-110.36dBV = -116.87dB (0dB=6.51dBV)
S/N of DAC is

106.0dB (measurement)

Therefore total S/N of op-amp circuit and DAC is

105.66dB (measurement: 105.5dB).

The total frequency response of this board is sum of the external filter and internal LPF of AK4527B.

These filters are effective to attenuate the high frequency noise since some measurement units is sensitive for
out-of-band noise.

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, AK4527B and TVDD of AK4112A.
+3.3V is supplied to AVDD and DVDD of AK4112A.

(2) Set up the evaluation mode and jumper pins. (See p.3.)

(3) Connect Optical or BNC connector.
[PORT2] (OPT_IN) : Optical input to RX1 of AK4112A
[J10] (RX2) : BNC input to RX1 of AK4112A

(4) Power on.
The AK4527B, AK4112A and AK4353 should be reset once bringing PDN(SW1) "L" upon power-up.

(5) Adjust the interface format

Serial control is needed after the reset by SW1. The default value for interface format of
AK4527B, AK4112A, and AK4353 is "Right justified, 20 bit", "Left justified, 24 bit", and "I

S", respectively.

The software "4527.exe" packed with the AKD4527B is used for the set-up of the AK4527B.

Evaluation mode 1 : DIF1-0 bit of the AK4527B should be set to "11" .

Evaluation mode 2, 3: DIF1-0 bit of the AK4527B should be set to "10".
Evaluation mode 4 : AK4112A and AK4527B should be set to adjust the format of DSP.

(6) Set up software.

The control mode of AK4527B and AK4112A is fixed to "serial".

The AKD4527B can be controlled via the printer port (parallel port) of IBM-AT
compatible PC. Connect PORT3(uP-I/F) with PC by 10-line flat cable
packed with the AKD4527B.

Take care of the direction of connector. There is a mark at pin#1.

The pin layout of PORT3 is as Figure 2. Figure 2. PORT3 pin layout

AK4353 Control Program operation manual

Connect IBM-AT compatible PC with Eva-board by 10-line type flat cable (packed with Eva-board).
Take care of the direction of 10pin Header (Refer to manual of Eva-board).

Start up "WINDOWS 95" or "WINDOWS 98".

Insert the floppy-disk packed with Eva-board into the floppy-disk drive.

Set up "MS-DOS" from start menu.

Change directory to the floppy-disk drive(ex.a:) at MS-DOS prompt.

Type "4353".

Then follow the displayed comment (See the following).
