LM2439

Monolithic Triple 9.5 ns CRT Driver

n Well matched with LM1279 video preamp

n 0V to 5V input range

n Stable with 0 pF–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

General Description

The LM2439 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.

Applications

n 1024 x 768 Displays up to 70 Hz Refresh

n Pixel clock frequencies up to 75 MHz

n Monitors using video blanking

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

molded plastic power package. See Thermal Considerations

section.

Features

n Dissipates approximately 50% less power than the

LM2406
