DESCRIPTION
The TDA8146 is a monolithic integrated circuit in a
14 pin dual-in-line plastic package.
The TDA8146 is des igned for use in th e east-wes t
pin-cushion correction by dr iving a diode modulator
in TV and monitor applications.
Since the parabola current generator is programmable the device can operate with different CRTs.
