SEL
Switches the input of the 3x amplifier. When
SEL is at Low level, V
IN1
is selected. When
SEL is at High level, V
IN2
is selected.
5
CE
Standby function ON/OFF selector. In stand-
by state when High.
19
TEST
Fix to V
SS
for normal use.
6
CLE
When CLE = Low: Clamp function is enabled.
When CLE = High: Clamp function is disabled,
and only the normal A/D converter function is
enabled.
18
CLK
Clock Input.
20
CLP
Inputs the clamp pulse to Pin 20 (CLP).
Clamps the High interval signal voltage.

REF
Clamp reference voltage input. Clamps so
that the reference voltage and the clamp inter-
val ADIN input signal are equal. The reference
voltage is more than 0.5V.
