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

Fully integrated, few external components
Maximum 2.5 A (p-p) deflection current
No additional components in combination with the
deflection controller family TDA485x and SAA4856
