DESCRIPTION

The TDA8145 is a monolithic integrated circuit in a 8 pin minidip plastic package designed for use in the square C.R.T. east-west pin-cushion correction by driving a diode modulator in TV and moni tor applications.

FEATURES SUMMARY

■ LOW DISSIPATION

■ SQUARE GENERATOR FOR PARABOLIC CURRENT SPECIALLY DESIGNED FOR SQUARE C.R.T. CORRECTION

■ EXTERNAL KEYSTONE ADJUSTMENT (symmetry of the parabola)

■ INPUT FOR DYNAMIC FIELD CORRECTION (beam current change)

■ STATIC PICTURE WIDTH ADJUSTMENT

■ PULSE-WIDTH MODULATOR

■ FINAL STAGE D-CLASS WITH ENERGY REDELIVERY

■ PARASITIC PARABOLA SUPPRESSION, DURING FLYBACK TIME OF THE VERTICAL SAWTOOTH
