1-5 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/ms

- 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
