LM2413
Monolithic Triple 3 nsec CRT Driver
General Description
The LM2413 is an integrated high voltage CRT
driver circuit designed for use in high resolution
color monitor applications. 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 -14 and
can drive CRT capacitive loads as well as resistive
loads presented by 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 on page 6.
