LM2445
Monolithic Triple 7.5 ns CRT Driver
General Description
The LM2445 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.
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.
