Product specification

Vertical deflection power amplifier for
monitors

TDA4860

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 160 Hz

High linear sawtooth signal amplification

Possibility of guarding the deflection

Voltage stabilizer.

GENERAL DESCRIPTION

The TDA4860 is a vertical power amplifier for differential
input signals suitable for colour monitor/TV systems with
deflection frequencies up to 160 Hz.
