4-7 STV5109
The STV5109 includes three video amplifiers designed with a high voltage bipolar/CMOS/DMOS technology(BCD).
It drives directly the three cathodes. and is protected against flashovers. Tanks to its three cathode current output,
the STV5109 can be used with both parallel and sequential sampling applications.

Green Output
Input of the "blue" amplifier. It is a virtual ground with 3.85V bias voltage and
75 microamperes input bias current.
Low voltage power supply. typically 12V.
Input of the "green" amplifier. It is a virtual ground with 3.85V bias voltage and
75 microamperes input bias current.
Input of the "red" amplifier. It is a virtual ground with 3.85V bias voltage and
75 microamperes input bias current.
High voltage Power supply, typically 220V.
Provides the video processor with a copy of the DC current flowing into the red
cathode, for automatic cut-off or gain adjustment, If this control is not used,
Pin 6 must be grounded.
Output driving the red cathode. Pin 7 is internally protected against CRT arc
discharges by a diode limiting the output voltage to V
DD
.
Also connected to the heatsink.
Output driving the feedback resistor network for the red amplifier.
Output driving the green cathode. Pin 10 is internally protected against CRT arc
discharges by a diode limiting the output voltage to V
