TEA5101A - ST Microelectronics

TEA5101A RGB HIGH VOLTAGE VIDEO AMPLIFIER

The TEA5101A 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 TEA5101A can be used with both parallel and sequential sampling applications. PIN CONNECTIONS (top view) MULTIWATT 15 (Plastic.

Features

2 3 4 5 6 Function Blue Input VCC Green Input Red Input VDD Red Cathode Current Description Input of the ”blue” amplifier. It is a virtual ground with 3.8V bias voltage, 15 microamperes input bias current with 14kΩ 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.
