Local Sensors
Local Sensing
Local sensors are located relatively close to their signal
conditioning circuits, and the noise environment is not
severe; most of these sensors are single ended (not
differential). Non-inverting amplifiers are a good choice for
amplifying most of these sensors’ output because they have
high input impedance, and require a minimal amount of
discrete components.
