Wireless Current Sense Circuit Floats with Sense Resistor

Kris Lokere - Strategic Applications Manager Apr 25th 2017
Introduction Measuring the current that flows through a sense resistor seems easy. Amplify the voltage, read it with an ADC, and now you know what the current is. But it gets more difficult if the sense resistor itself sits at a voltage that is very different from system ground. Typical solutions bridge that voltage difference ...
