Tda6107Q - Daewoo DTH-29U3 Service Manual

4.8 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/
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
