LM2415
Monolithic Triple 5.5 ns CRT Driver
General Description
The LM2415 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 chan-
nel has its gain internally set to −14 and can drive CRT ca-
pacitive loads as well as resistive loads present in other ap-
plications, 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
section.
