Product details

Temperature grade and environment

Rated for -40°C to 125°C, the INA199C2DCKR is qualified for industrial and automotive environments where the ambient temperature swings wide — think engine bay electronics, outdoor telecom cabinets, or factory-floor motor drives. The SC-70-6 package is small enough that thermal coupling to the PCB copper is important; a solid ground plane under the package helps keep the die temperature within the rated range when the sense resistor dissipates power nearby.

Lifecycle and sourcing reality

The INA199C2DCKR carries an active lifecycle status and is ROHS3 compliant. For a BOM line that needs a precision current-sense amplifier in a small package, this part is a straightforward fit with no end-of-life risk at this time.

Frequently asked questions

Does the INA199C2DCKR support high-side or low-side sensing?

It supports both high-side and low-side sensing. The input range extends from -0.1V to 26V, so it can measure current on the supply rail (high-side) or on the return path (low-side) without level shifting.

What is the closest functional second-source for the INA199C2DCKR?

The INA199B2QDCKRQ1 is a pin-compatible variant in the same INA199 family, but it is an automotive-grade (AEC-Q100) zero-drift version with ±1.5% accuracy. For a non-automotive design, the INA199C2DCKR is the standard commercial-grade part. The TPS26610DDFR and TPS26621DRCR are current regulators and electronic fuses — different functions, not direct substitutes.
