LM2429
Monolithic Triple Channel 15 MHz DTV Driver
General Description
The LM2429 is an integrated high voltage CRT driver circuit
designed for use in DTV 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 鈭?1 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.
