■ 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
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 correc-
tion by driving a diode modulator in TV and moni-
tor applications.
