Driver circuit for photodiode array with amplifier C9118 series
s Pin assignment of I/O connector
<CN1>
For connection to S8865 photodiode array
Connector type: 801-93-012-20-001 PRECI-DIP (made by DURTAL) or equivalent
Pin No. Terminal Name I/O
Description
1
RESET
O
Sensor scan start signal. Pulse width at High level nearly equals sensor integration
time.
2
CLK
O Sensor scan sync signal. Sensor starts scanning in synchronization with this signal.
3
Trig
I For A/D conversion timing signals. Positive logic
4
EXTST
O
High level at first stage during parallel or serial readout. At second and subsequent
stages during serial readout, this outputs the EOS pulse of preceding stage.
5
Vms
O
High level at first stage during parallel or serial readout. At second and subsequent
stages, this sets to Low level.
6
Vdd
O Sensor supply voltage
7
GND
- Sensor GND
8
EOS
I EOS (end of scan) signal of sensor. Negative logic
9
Video
I Video output signal. Positive polarity
10
Vref
O Reference voltage
11
Vgain
O Sensor gain switching H: high gain, L: low gain
12
Vpd
O Photodiode voltage
<CN2>
Used to connect the first stage to an external I/O during parallel readout or serial readout
For the second and subsequent stages during serial readout, CN2 is used to connect to CN3 at preceding stage.
Note 1) CN3 is installed only for C9118-01 (for serial readout).
Connector type: DF13-10P-1.25H (50) (made by Hirose Electric)
Pin No. Terminal Name I/O
Description
1
M-RESET
I
Sensor scan start signal. Pulse width at High level nearly equals sensor integration
time.
2
M-CLK
I
Sensor scan sync signal. Sensor and circuit start operating in synchronization with this
signal.
3
TRIGGER
O For A/D conversion timing signals. Positive logic
4
L-EOS
O EOS (end of scan) signal of all sensors during parallel or serial readout. Negative logic
NC (no connection) at first stage during parallel or serial readout. At second and
5
IN-START
I subsequent stages during serial readout, this receives the EOS pulse of preceding
stage.
6
GAIN
I External setting for sensor gain H: high gain, L: low gain
7
GND
- Circuit GND
8
+5 V
I +5 V power supply
9
VIDEO
O Video output signal. Positive polarity
10
A.GND
O Video GND
