Product details

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.

Frequently asked questions

Can INA215 be used for high-side current sensing?

Yes, the INA215 is designed for both high-side and low-side current sensing. Its common-mode input range extends from -0.3 V to 26 V, allowing it to sense current on the supply rail above ground.

What is the equivalent of INA215BIDCKR?

The INA4290A2IRGVR is a quad-channel current-sense amplifier with a 1.1 MHz bandwidth and 2 V/µs slew rate, but it is not a pin-compatible drop-in. For a single-channel replacement, the INA254A1IPWAR offers a zero-drift architecture with 350 kHz bandwidth. Verify the pinout and gain before substituting.
