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, 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. 1 NC COL OUT NC BAL / STRB NC NC BALANCE NC D Low Power Drain . . . 900 µW Typical With 5-V Supply Operates From ±15 V or From a Single Supply as Low as 3 V Output Drive Capability of 25 mA Emitter Output Can Swing Below Negative Supply Response Time . . . 1.2 µs Typ Low Input Currents: Offset Current . . . 2 nA Typ Bias Current . . . 15 nA Typ Wide Common-Mode Input Range: – 14.5 V to 13.5 V Using ±15-V Supply Same Pinout as LM111, LM211, LM311 Designed to Be Interchangeable With National Semiconductor LP311 NC EMIT OUT NC VCC+ NC D NC – No internal connection unctional block diagram BALANCE BAL / STRB The LP111 is characterized for operation over the full military temperature range of – 55°C to 125°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.
