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.°C to 70°

†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 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.

5. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable

ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ 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

a 1-mA load. Thus, these parameters define an error band and take into account the worst-case effects of voltage gain and input

impedance.

8. Voltages are with respect to EMIT OUT and VCC− tied together.

9. The strobe should not be shorted to ground; it should be current driven at 100 μA to 300 μA.
