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 is also 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.

AMP-PDK-EVM — Amplifier performance development kit evaluation module

The amplifier performance development kit (PDK) is an evaluation module (EVM) kit to test common operational amplifier (op amp) parameters and is compatible with most op amps and comparators. The EVM kit offers a main board with several socketed daughtercard options to fit package needs, allowing (...)
