LM2438

Monolithic Triple 13.5 ns CRT Driver

General Description

Features

n Well matched with LM1279 video preamp

n 0V to 5V input range

The LM2438 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 chan-

nel has its gain internally set to −14 and can drive CRT ca-

pacitive loads as well as resistive loads present in other ap-

plications, 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 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 60 Hz refresh

n Pixel clock frequencies up to 60 MHz

n Monitors using video blanking
