DESCRIPTION
Voltage adjustment pin of the ADC
black level clamp. This pin is biased
at 3.3 V from the inside of the IC.
Connect to the GND4 via a
capacitor if not used.
Signal input pin of the ADC.
Connect to the AGCOUT pin via a
capacitor.
This capacitor is also used as the
clamp capacitor of the ADC blank
level clamp.
No connection. It is recommended
to connect to GND for better heat
radiation and avoiding noise.
Pulse input pin of the ADC black
level clamp. Signal is clamped
when low.
When the ADOFS is opened, the
clamped level is set to make the
ADC output 61 (decimal).
Upper reference decoupling pin of
the ADC. Connect to the GND4 via
a capacitor.
Lower reference decoupling pin of
the ADC. Connect to the GND4 via
a capacitor.
