Product details

What this current-sense amp does on your board

The Texas Instruments INA180A2IDBVT is a single-channel current-sense amplifier that measures voltage across a shunt resistor and outputs a rail-to-rail voltage proportional to the load current. It runs on a supply span from 2.7 V to 5.5 V, draws 260 µA quiescent, and handles the -40°C to 125°C industrial range — so it fits motor-drive phase monitoring, DC-DC converter output sensing, and battery-management loops where the ambient is hot and the board has no fan.

Frequently asked questions

What is the bandwidth of INA180A2IDBVT?

The -3 dB bandwidth is 350 kHz, which is sufficient for tracking current in switching converters and motor drives operating up to a few hundred kilohertz.

What is the equivalent of INA180A2IDBVT?

A functional peer is the INA254A1IPWAR, also a current-sense amplifier with similar bandwidth (350 kHz) and supply range, but it uses a zero-drift topology that reduces input offset drift over temperature. The INA180A2IDBVT is the standard-drift option; choose the INA254 if offset drift matters in your precision loop.
