TDA6108JF
Triple Video Output Amplifier
1. Features
Typical bandwidth of 9.0 MHz for an output signal
of 60 V (peak-to-peak value)
High slew rate of 1850 V/ S
No external components required
Very simple application
Single supply voltage of 200 V
Internal reference voltage of 2.5 V
Fixed gain of 51

Thermal protection.
2. General Description
The TDA6108JF includes three video output
amplifiers in one plastic DIL-bent-SIL 9-pin
medium power (DBS9MPF) package (SOT
111-1), using high-voltage DMOS technolog
y, 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.
