Ordering number : EN7966 LA78041 Monolithic Linear IC TV and CRT Display Vertical Output IC with Bus Control Support Overview The LA78041 is a vertical deflection output IC for high image quality TV and CRT displays that supports the use of a bus control system signal-processing IC. The sawtooth waveform from the bus control system signal-processing IC can directly drive the deflection yoke (including the DC component). Color TV vertical deflection system adjustment functions can be controlled over a bus system by connecting the LA78041 to a Sanyo LA768X series or LA769XX series bus control system signal-processing IC. Since the LA78041 provides a maximum deflection current of 2.2Ap-p, it is optimal for large size CRTs. Functions • Low power operation achieved by using integrated cha [ ... ]
