Precision Measurement without Ground Offsets Using Differential Amplifier Input to A/D ADC, Ground Loop Circuit Diagram, Instrumentation Amplifier for Precision Sensor Measurement
Ground loop offset errors and ground noise are removed by a differential amplifier or instrumentation amplifier prior to A/D analog to digital conversion. The differential input amplifier mitigates ground loop errors. Precision measurement of non-isolated sensors. Simple op-amp circuit removes ground loop errors. Op-amp schematic removes ground noise.
