Single Comparators
The ability to operate from a single power supply of 5.0 V to 30 V or
$15 V split supplies, as commonly used with operational amplifiers,
makes the LM211/LM311 a truly versatile comparator. Moreover, the
inputs of the device can be isolated from system ground while the
output can drive loads referenced either to ground, the V
CC
or the V
EE
supply. This flexibility makes it possible to drive DTL, RTL, TTL, or
MOS logic. The output can also switch voltages to 50 V at currents to
50 mA, therefore, the LM211/LM311 can be used to drive relays,
lamps or solenoids.
