Product details

What this current-sense amp does and where it fits

The Texas Instruments INA199A3DCKT is a current-sense amplifier that monitors current by measuring the voltage drop across a shunt resistor. It handles common-mode voltages from -0.3 V up to 26 V.

Package and hand-solderability

The INA199A3DCKT comes in an SC-70-6 package — that's the six-lead variant of the SOT-363 footprint.

Temperature range and environment

Rated for -40°C to 125°C, this part covers industrial and automotive under-hood environments. It's happy in a motor-drive enclosure, an outdoor telecom power supply, or an engine-bay ECU. The wide temperature range also means the accuracy spec holds over the full span — no cold-start drift surprises.

Lifecycle and supply

The INA199A3DCKT is an active, current-production part with ROHS3 compliance. No last-time-buy or obsolescence risk on the horizon.

Frequently asked questions

Can INA199A3DCKT be used for high-side current sensing?

Yes, the INA199A3DCKT supports both high-side and low-side current sensing, as its input common-mode range extends from -0.3 V to 26 V.

What are the equivalent or replacement parts for INA199A3DCKT?

The INA199B2QDCKRQ1 is an automotive-grade (AEC-Q100) variant with the same ±1.5% accuracy and high/low-side sensing, but it has a narrower input voltage range starting at 0.1 V. For general-purpose use, the INA199A3DCKT is the standard version.
