The INA290A3IDCKT: Supply span from 2.7 V to 20 V; 3 µV typical input offset. 900 kHz bandwidth and 2 V/µs slew rate.
Minimum supply of 2.7 V; maximum 20 V. Quiescent current 370 µA.
Yes.
Yes, the INA290A3IDCKT is a current-sense amplifier that works for both high-side and low-side shunt measurements, as long as the common-mode voltage stays within the supply range.
The difference is in the gain version: the 'A3' suffix indicates a specific fixed gain (typically 100 V/V for the INA290A3), while the 'A2' variant has a different gain setting. The pinout and package are the same, so they are drop-in replacements if the gain matches the application requirement.
