Voltage comparator

DESCRIPTION

The LM111 series are voltage comparators that have input currents

approximately a hundred times lower than devices like the

µA710.

They are designed to operate over a wider range of supply voltages;

from standard

±15 V op amp supplies down to a single 3 V supply.

Their output is compatible with RTL, DTL, and TTL as well as MOS

circuits. Further, they can drive lamps or relays, switching voltages

up to 50 V at currents as high as 50mA.

Both the inputs and the outputs of the LM111 series 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-ORed.

Although slower than the

µA710 (200 ns response time versus 40 ns),

the devices are also much less prone to spurious oscillations. The

LM111 series has the same pin configuration as the

µA710 series.
