Current-sense amplifier for precision shunt monitoring
The Texas Instruments INA215BIDCKR is a single-channel current-sense amplifier in a SC-70-6 package. 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.
Package and mounting
Surface-mount SC-70-6 (also known as SOT-363). The 6-pin footprint is compact enough for space-constrained layouts on multi-layer boards. Tape & Reel and Cut Tape options are available for prototyping or production reels.
