LM2476
Monolithic Triple Channel 6.5 ns High Gain CRT Driver
and Bias Clamp
General Description
The LM2476 is a monolithic triple channel CRT driver and
triple bias clamp for low-cost color monitor applications. The
highly integrated IC contains three wide-band amplifiers for
driving the RGB cathodes of a CRT through external cou-
pling capacitors and three low-band clamp amplifiers for DC
restoration and cutoff adjustment of the video outputs. The
CRT drivers have a high, fixed gain of -27 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 a 19-lead TO-247 molded plastic
package and must be operated with a properly chosen heat
sink. See the Package Mounting and Thermal Consider-
ations sections for more information.
