What this part is — nanoPower current sense in a SOT-23-5
It measures load current by sensing the voltage drop across an external shunt resistor, outputting a voltage proportional to that current. The part draws only 1.1 µA supply current, making it a fit for battery-powered or always-on monitoring where every microamp matters. Gain-bandwidth product is 125 kHz, adequate for DC rail monitoring, overcurrent detection, and low-bandwidth current loops. Input offset voltage is 100 µV, which sets the minimum detectable shunt voltage floor.
