DESCRIPTION

· The TDA8145 is a monolithic integrated circuit in an 8-pin minidip plastic package.

· Designed for square CRT east-west pin-cushion correction by driving a diode modulator.

· Suitable for TV and monitor applications.

FEATURES

· Low dissipation.

· Square generator for parabolic current, specifically designed for square CRT 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.

APPLICATIONS

· TV and monitor applications requiring east-west pin-cushion correction.
