LM2436
Monolithic Triple 7.5 ns CRT Driver
General Description
The LM2436 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 −14 and can drive CRT
capacitive loads as well as resistive loads present in other
applications, limited only by the package’s power dissipation.
The IC is packaged in an industry standard 9-lead TO-220
molded plastic power package. See the Thermal Consider-
ations section for more information.
Features
n Well matched with LM1279 video preamp
n 0V 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 LM243X Family Pinout which is designed for
easy PCB layout
Applications
n 1024 x 768 displays up to 85 Hz refresh
n Pixel clock frequencies up to 100 MHz
n Monitors using video blanking
