Eagle Parts: INA138 high-side current shunt monitor

Posted on Tuesday, September 25th, 2012 in Eagle parts by DP

We added the INA138 high-side current monitor to our Eagle parts library. This is the part used in the Smoke Tester to read current through a voltmeter. It basically mirrors the current going through its shunt resistor to a load resistor. By playing with these values you can get an easy shunt current to output voltage ratio to make calculating current a no-brainer.
