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.

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.

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.
