Ordering number : EN7880A Monolithic Linear IC TV and CRT Display Vertical LA78040N Output IC with Bus Control Support Overview The LA78040N 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 LA78040N to a Sanyo LA768X series or LA769XX series bus control system signal-processing IC. Since the LA78040N provides a maximum deflection current of 1.7Ap-p, it is optimal for small and medium size CRTs. Functions • Built-in pump-up circui
