LM2469

Monolothic Triple 9nS High Gain CRT Driver

n 0V to 3.75V input range

n Stable with 0-20pF capacitive loads and inductive

peaking networks

n Maintains standard LM243X Family Pinout which is

designed for easy PCB layout

n Convenient TO-220 staggered 9 lead package style

General Description

The LM2469 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. Each

channel has its gain internally set to -20 and can drive CRT

capacitive loads as well as resistive loads present in other

applications, limited only by the package’s power dissipation.

Applications

n Up to 1024 X 768 at 70Hz

n Pixel clock frequencies up to 75MHz

n Monitors using video blanking

The IC is packaged in an industry standard 9 lead TO-220

molded plastic package.

Features

n Higher gain to match LM126X CMOS preamplifiers
