TDA8146 Datasheet | STMicroelectronics

EAST/WEST CORRECTION FOR RECTANGULAR TV-TUBES - . . . LOW POWER DISSIPATION PULSE WIDTH MODULATOR FOR SWITCH MODE OPERATION OUTPUT SINK CURRENT UP TO 800m A OUTPUT SOURCE CURRENT UP TO 100m A PARASITIC PARABOLA SUPPRESSION DURING VERTICAL FLYBACK VERTICAL CURRENT SENSE INPUTS GROUND PATIBLE PROGRAMMABLE PARABOLA CURRENT GENERATOR FOR DIFFERENT TV-TUBES EXTERNAL KEYSTONE ADJUSTMENT DIP14 (Plastic Package) ORDER CODE : TDA8146 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 programmable the device can operate with different CRTs.
