STV5111

STV5111 RGB HIGH VOLTAGE VIDEO AMPLIFIER s s s s s Bandwidth : 6MHz typical Supply Voltage : 200V typical Rise and Fall Time : 60ns TYPICAL CRT Cathode Current Outputs for Parallel or Sequential Cut-off or Drive Adjustment Flashover Protection DESCRIPTION The STV5111 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 STV5111 can be used with both parallel and sequential sampling applications. MULTIWATT 15 (Plastic Package) ORDER CODE: STV5111 Figure 1.
