STV5109
STV5109 is RGB High Voltage Video Amplifier manufactured by STMicroelectronics.
RGB HIGH VOLTAGE VIDEO AMPLIFIER s s s s s
Bandwidth : 8MHz typical Supply Voltage : 220V typical Rise and Fall Time : 50ns TYPICAL CRT Cathode Current Outputs for Parallel or Sequential Cut-off or Drive Adjustment Flashover Protection
DESCRIPTION The STV5109 includes three video amplifiers desi-gned with a high voltage bipolar/CMOS/ DMOS technology (BCD). It drives directly the three cathodes and is protected against flashovers. Thanks to its three cathode current outputs, the STV5109 can be used with both parallel and sequential sampling applications.

PIN FUNCTION
N° 1 2 3 4 5 6 Description Input of the “blue” amplifier. It is a virtual ground with 3.85V bias voltage and 75µA input bias current. Low voltage power supply, typically 12V. VCC Green Input Input of the “green” amplifier. It is a virtual ground with 3.85V bias voltage and 75µA input bias current. Red Input Input of the “red” amplifier. It is a virtual ground with 3.85V bias voltage and 75µA input bias current. High voltage power supply, typically 220V. VDD Red Cathode Current 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. Red Output Output driving the red cathode. Pin 7 is internally protected against CRT arc discharges by a diode limiting the output voltage to VDD. Ground Also connected to the heatsink. Red Feedback Output driving the feedback resistor network for the red amplifier. Green Output Output...
