LA78040N
Monolithic Linear IC
TV and CRT Display Vertical
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
mbus 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
ofunctions can be controlled over a bus system by connecting the LA78040N to a Sanyo LA768X series or LA769XX
.cseries 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.
