Monolithic Linear IC
LA78041
Overview
TV and CRT Display Vertical
Output IC with Bus Control
Support
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.
