| Ordering number: EN 5145 Monolithic Linear IC LA7832 Color TV Vertical Deflection Output Circuit Overview The LA7832 is a monolithic linear IC for vertical deflection output for small and mid-sized color television sets that requires few external components and dissipates little power. When used in conjunction with the LA7620 series of video chroma deflection ICs, the LA7800 series of deflection ICs, and the LA7850 series of display ICs, it is possible to create a stable and compact vertical output deflection circuit. Package Dimensions unit : mm 3075-SIP7H [LA7832] Features . High output. . Low power dissipation due to built-in pump-up circuit. . Few external components needed. . Thermal protection circuit built in.
