LM2426TE
Monolithic Triple Channel 30 MHz DTV Driver
General Description
The LM2426TE is an integrated high voltage CRT driver
circuit designed for use in HDTV 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 鈭?3 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 designed specifically to meet
high voltage spacing requirements. See Thermal Consider-
ations section.
