Philips Semiconductors Preliminary specification
Triple video output amplifier TDA6103Q
FEATURES
• High bandwidth: 7.5 MHz typical; 60 V (peak-to-peak
value)
• High slew rate: 1600 V/µs
• Simple application with a variety of colour decoders
• Only one supply voltage needed
• Internal protection against positive appearing
Cathode-Ray Tube (CRT) flashover discharges
• One non-inverting input with a low minimum input
voltage of 1 V
• Thermal protection
• Controllable switch-off behaviour.
GENERAL DESCRIPTION
The TDA6103Q includes three video output amplifiers in
one single in-line 9-pin medium power (SIL9MP) package
SOT111BE, using high-voltage DMOS technology,
intended to drive the three cathodes of a colour CRT.
