LM2408 Monolithic Triple 4 5 ns CRT Driver
December 1996
LM2408
Monolithic Triple 4 5 ns CRT Driver
General Description
The LM2408 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 The gain of
each channel is internally set at
b
15 and can drive CRT
capacitive loads as well as resistive loads presented by oth-
er applications limited only by the package鈥檚 power dissipa-
tion
The IC is packaged in an industry standard 11-Lead TO-220
molded plastic power package See thermal considerations
