Product Summary

The TDA4867J is a full bridge current driven vertical deflection booster. The TDA4867J is a power booster for use in colour vertical deflection systems for frame frequencies of 50 to 200 Hz. The circuit of the TDA4867J 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.

Parametrics

TDA4867J absolute maximum ratings: (1)IOUTB, IOUTA output current: 0 to ±1.6 A; (2)VFEEDB feedback voltage: 0 to VP V; (3)IFEEDB feedback current: 0 to ±5 mA; (4)VGUARD guard voltage: 0 to 10 V; (5)IGUARD guard current: 0 to ±5 mA; (6)Tstg storage temperature: -20 to +150 ℃; (7)Tamb ambient temperature: -20 to +75 ℃; (8)Tj junction temperature: -20 to +150 ℃.

Features

TDA4867J features: (1)Fully integrated, few external components; (2)Maximum 2.5 A (p-p) deflection current; (3)No additional components in combination with the deflection controller family TDA485x and SAA4856; (4)Pre-amplifier with differential high CMRR current mode inputs; (5)Low offsets; (6)High linear sawtooth signal amplification; (7)High efficient DC-coupled vertical output bridge circuit; (8)High deflection frequency up to 200 Hz.
