LM2459
Monolithic Single Channel 15 MHz DTV CRT Driver
General Description
The LM2459 is a single channel high voltage CRT driver
circuit designed for use in DTV applications. The IC contains
a high input impedance, wide band amplifier which directly
drives the cathode of a CRT. The amplifier has its gain
internally set to 51 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 staggered 7-lead TO-220 molded
plastic power package designed specifically to meet high
voltage spacing requirements. See Thermal Considerations
section.
