LM2460
LM2460 is Monolithic Triple Channel High Swing CRT Driver manufactured by National Semiconductor.
Description
The LM2460 is an integrated high voltage CRT driver circuit designed for use in high brightness 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
- 30 and can drive CRT capacitive loads as well as resistive loads present in other application, limited only by the package’s power dissipation.
The IC is packaged in an industry standard 9 lead TO-220 molded plastic package. n Stable with 0- 20 p F capacitive loads and inductive peaking networks n Convenient TO-220 staggered lead package style n Matched to LM126X/3X/4X pre-amplifier families
Applications n High brightness CRT monitors
Features n 0V to 5V input range n Capable of up to a 70 Vp-p output swing
