OverviewThe LA7840 is a vertical deflection output IC for TVs andCRT displays with excellent image quality that use a BUScontrol system signal processing IC. This IC can drive thedirect (even including a DC component) deflection yoke withthe sawtooth wave output from the BUS control system signalprocessing IC. When used in conjunction with Sanyo’s LA7615series of BUS control system signal processing ICs for TVs,this IC can process all color television signal system functionsthrough the BUS system. Because the maximum deflectioncurrent is 1.8 Ap-p, the LA7840 is suited for small andmedium screen sets.Features.. Low power dissipation due to built-in pump-up circuit . Vertical output circuit . Thermal protection circuit built in . Excellent crossover characteristics DC coupling possible
