Voltage Comparator
1.0 General Description
The LM111, LM211 and LM311are voltage comparators that
have input currents nearlya thousand times lower than
devices likethe LM106or LM710. They are also designedto
operate overa wider rangeof supply voltages: from standard
±15Vop amp supplies downtothe single5V supply usedfor logic. Their outputis compatible with RTL, DTL and TTL wellas MOS circuits. Further, they can drive lampsor
relays, switching voltagesupto 50Vat currentsas highas mA.
Boththe inputs andthe outputsofthe LM111, LM211or the
LM311 canbe isolated from system ground, and the output
can drive loads referredto ground,the positive supplyorthe
negative supply. Offset balancing and strobe capability are
provided and outputs canbe wire OR’ed. Although slower
thanthe LM106 and LM710 (200ns response timevs40ns)
the devices are also much less proneto spurious oscilla-
tions. The LM111 has the same pin configurationas the
LM106 and LM710.
The LM211is identicalto the LM111, except thatits perfor-
manceis specified overa −25˚Cto +85˚C temperature range
insteadof −55˚Cto +125˚C. The LM311 hasa temperature
rangeof 0˚Cto +70˚C.
2.0 Features Operates from single5V supply Input current: 150nA max. over temperature Offset current:20nA max. over temperature Differential input voltage range: ±30V Power consumption: 135 mWat ±15V
