Function
Oscillation prevention ca-
pacitor
If the parabola output oscil-
lates, a capacitor of several
10pF must be connected
between this pin and Pin10.

pF must be connected
between this pin and Pin9.
Control pin of the ampli-
tude of horizontal parabola
output.
If the current is increased
by inserting a resistor
between this pin and GND,
the amplitude decrease.
