Product details

Its 3 µV input offset and 500 pA input bias let you resolve microamp-level currents through a milliohm shunt without calibration, while the 37 kHz gain-bandwidth product sets the usable bandwidth for DC and slow-transient monitoring — adequate for battery fuel gauging, motor winding current, and power-rail supervision, but not for fast overcurrent detection where the signal changes in microseconds. The rail-to-rail output stage keeps the full ADC input range usable at low supply voltages.

The 1.7 V minimum supply span lets it run from a single Li-ion cell or a 1.8 V rail, and the 48 µA quiescent current keeps the power budget lean in battery-operated equipment. Surface-mount assembly on a standard SC-70-6 footprint; the Tape & Reel option suits automated pick-and-place for medium-to-high volume builds.

Frequently asked questions

Can INA190A2IDCKT replace INA190A1IDCKT?

The INA190A2IDCKT is a different gain variant within the same Zero-Drift series and SC-70-6 package. Both share the same pinout and supply range, so a direct replacement is possible if the gain (A2 vs A1) meets the system requirement. Verify the gain setting in your application before substituting.
