This is a current-sense amplifier (also called a current-shunt monitor) that senses the voltage drop across current-sense resistors at common-mode voltages from\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e–0.2 V to +26 V\u003c\/strong\u003e, independent of the supply voltage. The project was built using\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eINA4180\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003echip which integrates a matched resistor gain network in four, fixed-gain\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e20V\/V\u003c\/strong\u003e, this matched gain resistor network minimizes gain error and reduces the temperature drift. The board operates with a single\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e2.7-V to 5.5-V\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003epower supply.
