Product details

What this current sense amplifier does on your board

It operates from a 2.7 V to 36 V supply span, draws 200 µA quiescent current, and is specified over the -40°C to 125°C industrial temperature range.

For a current sense amplifier, the gain-bandwidth product sets the upper frequency where the gain starts to roll off. At 50 kHz, this part is suited for DC and low-frequency current measurements — think average current monitoring in a power supply or battery charger, not high-speed switching waveforms in a fast-switching converter. If your application needs to capture sub-microsecond current spikes or monitor switching edges above a few tens of kilohertz, you would look at a wider-bandwidth current sense amplifier like the INA254A1IPWAR (350 kHz GBW, 2.4 V/µs slew rate).

Frequently asked questions

What are the alternatives or equivalents for INA250A2PW?

The closest functional alternative in TI's portfolio is the INA254A1IPWAR, which offers a wider 350 kHz gain-bandwidth product and a 2.4 V/µs slew rate in a similar current sense amplifier role. The INA254A1IPWAR is a zero-drift topology, so it trades lower offset drift for higher bandwidth. Both parts share the same 2.7 V minimum supply and 16-TSSOP package, but the INA254A1IPWAR draws 1.8 mA supply current versus the INA250A2PW's 200 µA — a meaningful difference for battery-powered designs.
