GENERAL DESCRIPTION
●The TDA4867J is a power booster for use in colour vertical deflection systems for frame frequencies of 50 to 200 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 the deflection controller family TDA485x and SAA4856 the ICs offer an extremely advanced system solution.
●FEATURES
●• Fully integrated, few external components
