LM2413
Monolithic Triple 4 ns CRT Driver
General Description
The LM2413 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 鈭?4 and can
drive CRT capacitive loads as well as resistive loads present
in other applications, limited only by the package鈥檚 power
dissipation.
The IC is packaged in an industry standard 11 lead TO-220
molded plastic power package. See Thermal Considerations
on page 6.
