LM2406

Monolithic Triple 9 ns CRT Driver

General Description

The LM2406 is an integrated high voltage CRT driver circuit

designed for use in color monitor applications The IC con-

tains three high input impedance wide band amplifiers

which directly drive the RGB cathodes of a CRT The gain of

capacitive loads as well as resistive loads presented by oth-

er applications limited only by the package’s power dissipa-

tion

The IC is packaged in an industry standard 11 lead TO-220

molded plastic power package See thermal considerations
