PRECAUTIONS ON USE
Be sure to ground the pins of AV
DD5
, AV
DD3
, DV
DD
and V
RT
via high-frequency capacitor.
Place the high-frequency capacitor as close as possible to the pin.
You can minimize the power supply current dissipation due to the internal logic indetermination by making CE
to high on power turning on.
Pin No.

Digital output pin
18
CLK
Clock input pin
29
ADIN
A/D converter analog input pin.
Input range is V
RB
to V
RT
(0 to 1.5 V)
Relationship between analog input and digital output is defined by Test function.
23
V
RTC
Input pin for reference voltage adjustment amp (V
RT
reference voltage adjustment)
V
RT
is adjusted so that it is 1.5 V with the input pin opened.
22
V
RT
Reference voltage output pin on top side.
The voltage fed to V
RTC
is output.
1
V
RB
Reference voltage input pin on bottom side (0V)
25
V
IN1
Input pin 1 for 1:3 gain amp
Dual input selector for inverting amp
27
V
IN2
Input pin 2 for 1:3 gain amp
30
OPO
Input pin for 1:3 gain (at standby: high impedance)
4
SEL
Toggle input pin for dual input selector for 1:3 gain amp
Input "L": V
IN1
, Input "H": V
IN2
Test function
5
CE
Input pin for toggling standby function.
Input high signal brings the standby state to the A/D
converter, 1:3 gain amp, and reference voltage adjustment
amp.
32
