Gain control pin.
This pin’s bias govern the AGC output level.
Minimum gain at V
AGC
= 0 V
Maximum gain at V
AGC
= 5 V
Recommended to use by dividing AGC voltage
with externally resistor (ex.100 k
).

Gain control pin of video amplifier.
Maximum gain at G1A – G1B = short.
Minimum gain at G1A – G1B = open.
Gain is able to adjust by inserting arbitrary
resistor between 7pin and 8pin.
Refer to Equivalent circuit of pin14
and pin15.
