description/ordering information
The LP211 and LP311 devices are low-power versions of the industry-standard LM211 and LM311 devices.
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 LP211 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. In addition, offset balancing is available to minimize input offset voltage. Strobe capability also is
provided to turn off the output (regardless of the inputs) by pulling the strobe pin low.
The LP211 is characterized for operation from −25°C to 85°C. The LP311 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
CC+
and V
CC−
.
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.
5. Maximum power dissipation is a function of T
J
(max),
θ
JA
, and T
A
. The maximum allowable power dissipation at any allowable
ambient temperature is P
D
= (T
J
(max) − T
A
)/
θ
JA
. Operating at the absolute maximum T
J
of 150°C can affect reliability.
6. The package thermal impedance is calculated in accordance with JESD 51-7.

NOTES: 7. The offset voltages and offset currents given are the maximum values required to drive the output within 1 V of either supply with
