Many operational amplifiers exhibit phase ADR4525 0.1µF reversal when the voltage applied to the input is greater than the 4.12kΩ 4.37kΩ 200Ω maximum common-mode voltage. In some instances, this phase 6 reversal can cause permanent damage to the amplifier. In feedback 4.12kΩ 100Ω ADA14/0277-2 7 VOUT loops, it can result in system lockups or equipment damage.

Ensure, where possible, that input signal paths contain matching numbers and types of Calibration of the bridge is made at the minimum value of the components, to match the number and type of thermocouple temperature to be measured by adjusting R until the output is P junctions. For example, dummy components such as zero value zero. resistors can be used to match real resistors in the opposite input To calibrate the output span, set the full-scale and linearity path. Place matching components in close proximity to each other, potentiometers to midpoint, and apply a 500°C temperature to and orient them in the same manner. Ensure that leads are of equal the sensor, or substitute the equivalent 500°C RTD resistance. length so that thermal conduction is in equilibrium.

ADA4077-1/ADA4077-2/ADA4077-4 Data Sheet LONG-TERM DRIFT TEMPERATURE HYSTERESIS The stability of a precision signal path over its lifetime or between In addition to stability over time as described in the Long-Term calibration procedures is dependent on the long-term stability Drift section, it is useful to know the temperature hysteresis, of the analog components in the path, such as op amps, references, that is, the stability vs. cycling of temperature. Hysteresis is an and data converters. To help system designers predict the long- important parameter because it tells the system designer how term drift of circuits that use the ADA4077-1/ADA4077-2/ closely the signal returns to its starting amplitude after the ADA4077-4, Analog Devices measured the offset voltage of ambient temperature changes and subsequent return to room multiple units for 10,000 hours (more than 13 months) using a temperature.

To replicate real-world system performance, the devices 125°C to −40°C and back to room temperature. The dotted line under test (DUTs) were soldered onto an FR4 PCB using a is an initial preconditioning cycle to eliminate the original standard reflow profile (as defined in the JEDEC J-STD-020D temperature-induced offset shift from exposure to production standard), as opposed to testing them in sockets. This manner solder reflow temperatures. In the three full cycles, the offset of testing is important because expansion and contraction of the hysteresis is typically only 1 µV, or 1.5% of its 65 µV maximum PCB can apply stress to the integrated circuit (IC) package and offset voltage over the full operating temperature range.
