4.4  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. 
 

§ Typical bandwidth of 5.5 MHz for an output signal of 60 Vpp 
§ High slew rate of 900V/

µ

s 

§ 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
