LM111JAN Voltage Comparator
April 2, 2008
LM111JAN
Voltage Comparator
General Description
The LM111 is a voltage comparator that has input currents
nearly a thousand times lower than devices such as the
LM106 or LM710. It is also designed to operate over a wider
range of supply voltages: from standard ±15V op amp sup-
plies down to the single 5V supply used for IC logic. The
output is compatible with RTL, DTL and TTL as well as MOS
circuits. Further, it can drive lamps or relays, switching volt-
ages up to 50V at currents as high as 50 mA.
Both the inputs and the outputs of the LM111 can be isolated
from system ground, and the output can drive loads referred
to ground, the positive supply or the negative supply. Offset
balancing and strobe capability are provided and outputs can
be wire OR'ed. Although slower than the LM106 and LM710
(200 ns response time vs 40 ns) the device is also much less
prone to spurious oscillations. The LM111 has the same pin
configuration as the LM106 and LM710.
