TDA6108AJF
Triple video output amplifier
Rev. 03 — 20 April 2005
Product data sheet
1. General description
The TDA6108AJF contains three video output amplifiers which are intended to drive the
three cathodes of a color CRT. 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.
2. Features
s Typical bandwidth of 9.0 MHz for an output signal of 60 V (p-p)
s High slew rate of 1310 V/µs
s No external components required
s Very simple application
s Single supply voltage of 200 V
s Internal reference voltage of 2.5 V
s Fixed gain of 81
s Black-Current Stabilization (BCS) circuit with voltage window from 1.5 V to 6 V and
current window from +100 µA to −10 mA
s Thermal protection

8.1 Thermal protection
The internal thermal protection circuit gives a decrease of the slew rate at high
temperatures: 10 % decrease at 130 °C and 30 % decrease at 145 °C (typical values on
the spot of the thermal protection circuit).
