TDA6107

Features
· Typical bandwidth of 5.5 MHz for an output signal of 60 V (p-p)
· High slew rate of 900 V/ms
· No external components required
· Very simple application
· Single supply voltage of 200 V
· Internal reference voltage of 2.5 V
· Fixed gain of 50
· Black-Current Stabilization (BCS) circuit with voltage window from 1.8 to 6 V and current window from -100
mA to 10 mA

General Description
The TDA6107JF 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.
