Ultrahigh-Performance Differential-Output Programmable-Gain Instrumentation Amplifier

Data-acquisition systems and PLCs require versatile high-performance analog front ends that interface with a variety of sensors to measure signals accurately and reliably. Depending on the magnitude of the voltage or current being measured, the signal may need to be amplified or attenuated to match the full-scale input range of the ADC used for further digital processing and feedback control.
