LM2462
Monolithic Triple 3 ns CRT Driver
General Description
The LM2462 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
channel has its gain internally set to −20 and can drive CRT
capacitive loads as well as resistive loads present in 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
section.
Features
n Higher gain to match LM126X CMOS preamplifiers
n 0V to 3.75V input range
n Stable with 0–20 pF capacitive loads and inductive
peaking networks
n Convenient TO-220 staggered lead package style
n Maintains standard LM240X Family pinout which is
designed for easy PCB layout
Applications
n 1600 x 1200 displays up to 85Hz refresh
n Pixel clock frequencies up to 230 MHz
n Monitors using video blanking
