LM2459

Monolithic Single Channel 15 MHz DTV CRT Driver

General Description

Features

n 15MHz bandwith at 130V_PPoutput swing

n 0V to 4V input range

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.

n Greater than 130V_PPoutput swing capability

n Stable with 0–20 pF capacitive loads and inductive

peaking networks

n Transient response improvement option via pin 6 (EM)

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.

Applications

n AC coupled DTV applications using the 480p format as

well as standard NTSC and PAL formats.
