Technical details

It measures current by amplifying the voltage drop across a shunt resistor, outputting a rail-to-rail signal proportional to the load current. With a gain-bandwidth product of 45 kHz and an input offset voltage of 3 µV, it resolves small differential signals accurately without external trimming. The part operates from 1.7 V to 5.5 V supply and draws 48 µA quiescent current, making it suitable for battery-powered and always-on monitoring in industrial and automotive systems.

Supply range and bias — fit for low-side and high-side shunts

Input bias current is 500 pA.

Listed as current production (active) with ROHS3 compliance.

Package and mounting — SC-70-6 footprint

Surface-mount SC-70-6 (also known as SOT-363).
