File name Tda4866.pdf INTEGRATED CIRCUITS DATA SHEET TDA4866 Full bridge current driven vertical deflection booster Product specification Supersedes data of 1995 Aug 31 File under Integrated Circuits, IC02 1996 Oct 10 Philips Semiconductors Product specification Full bridge current driven vertical deflection booster FEATURES · Fully integrated, few external components · No additional components in combination with the deflection controller TDA4850/51/55 · Pre-amplifier with differential high CMRR current mode inputs · Low offsets · High linear sawtooth signal amplification · High efficient DC-coupled vertical output bridge circuit · Powerless vertical shift · High deflection frequency up to 140 Hz TDA4866 · Power supply and flyback supply voltage independent adjustable to optimize power consumption and flyback time · Excellent transition behaviour during flyback · Guard circuit for screen protection. GENERAL DESCRIPTION The TDA4866 is a power amplifier for use in 90 degree colour vertical deflection systems for frame frequencies of 50 to 140 Hz. The circuit provides a high CMRR current driven differential input. Due to the bridge configuration of the two output stages DC-coupling of the deflection coil is achieved. In conjunction with TDA4850/51/55 the ICs offer an extremely advanced system solution.
