Product details

Current sense with ±1.5% accuracy across a wide input range

The Texas Instruments INA199A3RSWR is a current sense amplifier that monitors current via high- or low-side sensing, with a ±1.5% accuracy spec that holds across the -0.3 V to 26 V input range. It operates from -40°C to 125°C, making it suitable for industrial and automotive environments where temperature extremes are common.

The supplier device package is 10-UQFN (1.8x1.4), so the PCB footprint matches the standard UFQFN land pattern for this pin count.

Frequently asked questions

What is the accuracy of the INA199A3RSWR?
