noise testing
Figure shows test circuit 0.1-Hz 10-Hz peak-to-peak noise measurement OP27 OP37. frequency response this noise tester indicates that 0.1-Hz corner defined only zero. Because time limit acts additional zero eliminate noise contributions from frequency band below test time measure 0.1-Hz 10-Hz noise should exceed seconds. Measuring typical 80-nV peak-to-peak noise performance OP27 OP37 requires following special test precautions: device should warmed least five minutes. operational amplifier warms offset voltage typically changes chip temperature increasing from 10°C 20°C starting from moment power supplies turned 10-s measurement interval, these temperature-induced effects easily exceed tens nanovolts. similar reasons, device should well shielded from currents eliminate possibility thermoelectric effects excess nanovolts, which would invalidate measurements. Sudden motion vicinity device should avoided, produces feedthrough effect that increases observed noise.

When measuring noise large number units, noise-voltage density test recommended. 10-Hz noise-voltage density measurement correlates well with 0.1-Hz 10-Hz peak-to-peak noise reading since both results determined white noise location corner frequency.
