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
