LM2419
Triple 65 MHz CRT Driver
General Description
The LM2419 contains three wide bandwidth large signal
amplifiers designed for large voltage swings The amplifiers
have a gain of
15 The device is intended for use in color
b
CRT monitors and is a low cost solution to designs conform-
ing to 1024 x 768 display resolution
The device is mounted in the industry standard 11-lead
TO-220 molded power package The heat sink is electrically
isolated and may be grounded for ease of manufacturing
and EMI RFI shielding
