description

The LP1 11, LP21 1, LP31 1 are low-power versions
of the industry standard LM111, LM211, LM311.
They take advantage of stable, high-value,
ion-implanted resistors to perform the same
function as the LM311 series, with a 30:1
reduction in power consumption but only a 6:1
slowdown in response time. They are well suited
for battery-powered applications and all other
applications where fast response times are not
needed. They operate over a wide range of supply
voltages, from ±18 V down to a single 3-V supply
with less than 300-µA current drain, but are still
capable of driving a 25-mA load. The LP111,
LP21 1, and LP311 are quite easy to apply free of
oscillation if ordinary precautions are taken to
minimize stray coupling from the output to either
input or to the trim pins.

The LP1 1 1 is characterized for operation over the
full military temperature range of – 55°C to 125°C.
The LP211 is characterized for operation from
– 25°C to 85°C, and the LP31 1 is characterized for
operation from 0°C to 70°C.

†

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated in the recommended operating conditions section of this
specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values, unless otherwise noted, are with respect to the midpoint between V

2. Differential input voltages are at IN+ with respect to IN –.

3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage of ±15 V, whichever is less.

4. The output may be shorted to ground or to either power supply.
