Product Summary

The LM2452TB/NOPB is a triple channel high voltage DC coupled CRT driver circuit designed for use in DTV applications. The LM2452TB/NOPB IC contains three high input impedance, wide band amplifiers which directly drive the RGB cathodes of a CRT. Each amplifier has a summing input where the DC level of the output is controlled by a low voltage DC input voltage. Normally the DC input voltage is from a DAC. Each channel of the LM2452TB/NOPB has its gain internally set to -54 and can drive CRT capacitive loads as well as resistive loads present in other applications, limited only by the power dissipation of the package.
