LM2459
LM2459 is Monolithic Single Channel 15MHz DTV CRT Driver manufactured by Texas Instruments.
FEATURES
- 2 15MHz Bandwidth at 130VPP Output Swing
- 0V to 4V Input Range
- Greater than 130VPP Output Swing Capability
- Stable With 0- 20 p F Capacitive Loads and
Inductive Peaking Networks

Pin 6 (EM)
APPLICATIONS
- AC Coupled DTV Applications Using the 480p Format as well as Standard NTSC and PAL Formats
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 (KCS) molded plastic power package designed specifically to meet high voltage spacing requirements. See THERMAL CONSIDERATIONS section.
