Ordering number: EN5150B Monolithic Linear IC LA7845N Vertical Deflection Output Circuit Overview The LA7845N is a vertical deflection output IC for TVs and CRT displays with excellent image quality that use a BUS control system signal processing IC. This IC can drive the direct (even including a DC component) deflection yoke with the sawtooth wave output from the BUS control system signal processing IC. When used in conjunction with Sanyo’s LA7615 series of BUS control system signal processing ICs for TVs, this IC can process all color television signal system functions through the BUS system. Because the maximum deflection current is 2.2 Ap-p, the LA7845N is suited for large screen sets, being capable of driving screens ranging from 33 inches to 37 inches.
