LM2402

Monolithic Triple 3 ns CRT Driver

General Description

The LM2402 is an integrated high voltage CRT driver circuit

designed for use in high resolution color monitor applica-

tions. The IC contains three high input impedance, wide

band amplifiers which directly drive the RGB cathodes of a

CRT. Each channel has its gain internally set to −14 and can

drive CRT capacitive loads as well as resistive loads pre-

sented 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 5.

Features

n Rise/fall times typically 3.0/2.8 ns with 8 pF load at

40 V

PP

n Well matched with LM2202 video preamps

n Output swing capability: 50 VPP for VCC = 80V

n 1V to 5V input range

n Stable with 0-20 pF capacitive loads and inductive

peaking networks

n Convenient TO-220 staggered lead package style

n Standard LM240X family pinout which is designed for

easy PCB layout

Applications

n CRT driver for color monitors with display resolutions up

to 1600 x 1200

n Pixel clock frequency up to 200 MHz
