LM2467

Monolithic Triple 7.5 ns CRT Driver

General Description

Features

n Higher gain to match LM126X CMOS preamplifiers

n 0V to 3.75V input range

The LM2467 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.

n Stable with 0–20 pF capacitive loads and inductive

peaking networks

n Convenient TO-220 staggered lead package style

n Maintains standard LM243X Family pinout which is

designed for easy PCB layout

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

molded plastic power package. See Thermal Considerations

section.

Applications

n 1024 x 768 displays up to 85 Hz refresh

n Pixel clock frequencies up to 95 MHz

n Monitors using video blanking
