4-6 TDA6107Q

The TDA6107Q includes three video output amplifiers in one plastic DIL-Bent-SIL 9-pin medium power package, using high voltage DMOS technology, and is intended to drive the three cathodes of a colour CRT directly. To obtain maximum performance, the amplifier should be used with black-current control.

Features

-Typical bandwidth of 5.5 MHz for an output signal of 60 Vpp

-High slew rate of 900V/ s

-No external components required

-Very simple application

-Single supply voltage of 200V

-Internal reference voltage of 2.5 V

-Fixed gain of 50.

-Black-current stabilisation (BCS) circuit

-Thermal protection
