TDA8146 EAST/WEST CORRECTION FOR RECTANGULAR TV-TUBES .. .. . . . . LOW POWER DISSIPATION PULSE WIDTH MODULATOR FOR SWITCH MODE OPERATION OUTPUT SINK CURRENT UP TO 800mA OUTPUT SOURCE CURRENT UP TO 100mA PARASITIC PARABOLA SUPPRESSION DURING VERTICAL FLYBACK VERTICAL CURRENT SENSE INPUTS GROUND COMPATIBLE 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.
