monitors

Product specification

TDA4861

FEATURES

• Vertical pre-amplifier with differential inputs

• Powerless vertical shift

• Flyback voltage generation suitable for two operating

modes (doubling the supply voltage or external supply

for the short flyback time, this achieves a minimum of

power dissipation)

• Vertical output stage with thermal and SOAR protection

• High deflection frequency up to 140 Hz

• High linear sawtooth signal amplification

• Possibility of guarding the deflection

• Voltage stabilizer.

GENERAL DESCRIPTION

The TDA4861 is a vertical power amplifier for differential

input signals suitable for colour monitor/TV systems with

deflection frequencies up to 140 Hz.
