What this current sense amplifier does on your board
The Texas Instruments INA250A2PW is a single-channel current sense amplifier in a 16-TSSOP package. 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.
Slew rate and gain bandwidth — what they mean for your measurement
The INA250A2PW has a gain-bandwidth product of 50 kHz and a slew rate of 0.2 V/µs. 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. The 0.2 V/µs slew rate means the output voltage cannot change faster than 0.2 V per microsecond, which limits the part's ability to follow fast current transients. 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).
Lifecycle and sourcing reality
The INA250A2PW carries an Active lifecycle status and is ROHS3 compliant. For a BOM line that needs a current sense amplifier in a 16-TSSOP footprint with a 2.7 V to 36 V supply range, this part is a current-production choice with no near-term obsolescence risk.
