DESCRIPTION

The TDA8146 is a monolithic integrated circuit in a

14 pin dual-in-line plastic package.

The TDA8146 is designed for use in the east-west

pin-cushion correction by driving a diode modulator

in TV and monitor applications.

Since the parabola current generator is program-

mable the device can operate with different CRTs.
