8.2.1.2 Detailed Design Procedure

The floating ground reference (GND1) is derived from the end of the shunt resistor, which is connected to the negative input of the AMC1100 (VINN). If a four-terminal shunt is used, the inputs of the AMC1100 are connected to the inner leads and GND1 is connected to one of the outer shunt leads. The differential input of the AMC1100 ensures accurate operation even in noisy environments.

The differential output of the AMC1100 can either directly drive an analog-to-digital converter (ADC) input or can be further filtered before being processed by the ADC.
