function as the LM311 series, with a 30:1						CC
reduction in power consumption but only a 6:1
slowdown in response time. They are well suited
for battery-powered applications and all other				NC ± No internal connection
applications where fast response times are not
needed. They operate over a wide range of supply				unctional block diagram
voltages, from ±18 V down to a single 3-V supply
with less than 300-μA current drain, but are still				BALANCE
capable of driving a 25-mA load. The LP111,				BAL / STRB
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				IN+						COL OUT
input or to the trim pins.

The LP111 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 LP311 is characterized for operation from 0°C to 70°C.

²Stresses 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 VCC+ and VCC± .

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.
