The ACT001-10E is a high-sensitivity, inline analog TMR current sensor for AC or DC measurements. An integrated current strap senses current, and a TMR bridge sensor element provides a Wheatstone bridge differential output. The output is bipolar and proportional to the current through the strap. The sensor has a -500 mA to +500 mA linear range, with a typical sensitivity of 0.04 mV/V-mA. The part comes in an ultraminiature DFN6 package.
