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.
