LM2406
LM2406 is Monolithic Triple 9 ns CRT Driver manufactured by National Semiconductor.
Description
The LM2406 is an integrated high voltage CRT driver circuit designed for use in color monitor applications The IC contains three high input impedance wide band amplifiers which directly drive the RGB cathodes of a CRT The gain of each channel is internally set at b14 5 and can drive CRT capacitive loads as well as resistive loads presented by other applications limited only by the package’s power dissipation The IC is packaged in an industry standard 11 lead TO-220 molded plastic power package See thermal considerations on page 4
