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.

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.
