Triple 30-MHz CRT driver for VGA
The LM2418 is a triple 30-MHz CRT driver designed to directly drive CRT
cathodes for VGA color graphics displays. Each of the device's three
amplifiers has a nominal voltage gain of 19, with 1.0 dB of gain matching
between amplifiers. Output rise and fall time is typically 12 ns with an
8-pF load. The LM2418 is able to operate from a 90-V supply and has an
output voltage swing of up to 65 Vp-p. It is available in an 11-lead
TO-220 package. The heat sink tab is isolated and may be grounded to
improve rfi shielding. ($6.90 ea/100–samples available now.) National
