Some operational amplifiers (op amps) have an inductive open-loop output impedance, which can be more complex to stabilize than op amps with resistive output impedances. One of the most common ...

The force signal from the strain gage in the load cell feeds back to the motor-drive amplifier, forming a closed-loop force-control system. Industrial applications such as welding, grinding, and ...

The loop output can go directly to an ADC (analog-to-digital converter) or DMM in the configuration of K22 shown. If, however, filtering is needed to reduce noise during measurements, K22 can be ...
