Current-sense amplifier for precision shunt monitoring
It measures the voltage drop across a shunt resistor and outputs a ground-referenced voltage proportional to the load current. The 40 kHz gain-bandwidth product sets the upper frequency of the current waveform it can faithfully reproduce — adequate for DC rail monitoring, battery charge/discharge loops, and overcurrent detection in motor drives or power supplies. The 1 µV input offset voltage means the part resolves small shunt drops without external trimming, which matters when the full-scale shunt voltage is in the tens of millivolts.
Surface-mount SC-70-6 (also known as SOT-363). Tape & Reel and Cut Tape options are available for prototyping or production reels.
