1C DESCRIPTION
4 TDA6107AJF
The TDA6107AJF includes three video output amplifiers and is intended to drive the three
cathodes of a colour CRT directly. The device is contained in a plastic DIL-bent-SIL 9-pin
medium power(DBS9MPF) package, and uses high-voltage DMOS technology.
To obtain maximum performance, the amplifier should be used with black-current control.
4.1 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 81.
- Black-current stabilisation (BCS) circuit with voltage window from 1.8 to 6 V and current
window form 100uA to -10mA
- Thermal protection
- Internal protection against positive flashover discharges appearing on the CRT
