The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

A wide common mode input voltage range, from ground to within 2V of the supply voltage, ensures that the ZXCT1050 current monitor from Zetex Semiconductors will continue to provide accurate current ...
