TEA5101B RGB HIGH VOLTAGE VIDEO AMPLIFIER . . . . . . PRELIMINARY DATA BANDWIDTH : 10MHz TYPICAL RISE AND FALL TIME : 50ns TYPICAL CRT CATHODES CURRENT OUTPUTS FOR PARALLEL OR SEQUENTIAL CUT-OFF OR DRIVE ADJUSTMENT FLASHOVER PROTECTION POWER DISSIPATION : 3.5W ESD PROTECTED DESCRIPTION The TEA5101B includes three video amplifiers desi-gned with a high voltage DMOS/bipolar technology. It drives directly the three CRT cathodes. The device is protected against flashovers. Due to its three cathode current outputs, the TEA5101B can be used with both parallel and sequential sampling applications.

It is a virtual ground with 3.8V bias voltage, 15 microamperes input bias current with 14k input resistance. Low voltage power supply, typically 12V. See Pin 1. See Pin 1. High voltage power supply, typically 200V. 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 VDD. Also connected to the heatsink. Output driving the feedback resistor network for the red amplifier. See Pin 7. See Pin 6. See Pin 9. See Pin 6.
