LM2418 Triple 30 MHz CRT Driver
General Description
The LM2418 contains three large signal voltage amplifiers
designed to directly drive CRT cathodes for VGA Color
Graphics Displays Output swings greater than 50 V
achieved with a 90V power supply The nominal voltage
gain of each amplifier is
19 with gain matching of 1 0 dB
b
between amplifiers
Packaging is the industry standard molded 11 lead TO-220
The heatsink tab is isolated and may be grounded to im-
prove RFI shielding and simplify assembly
