Philips Semiconductors Product specification
Vertical deflection power amplifier for
monitors
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.
