It outputs a ground-referenced voltage proportional to the sensed current, eliminating the need for a separate level shifter. The ±1.5% accuracy over the full temperature range keeps the power-monitoring budget tight enough for most industrial and automotive loads without requiring a precision instrumentation amplifier. ## Temperature grade and environment Rated for -40°C to 125°C operation, this part is qualified for industrial enclosures, outdoor telecom cabinets, and under-hood automotive environments. No separate automotive-grade variant is needed for most chassis and cabin-domain applications. ## Lifecycle and sourcing It is ROHS3 compliant.","metaTitle":"INA199A2RSWT Current Sense Amplifier, ±1.5% Accuracy","metaDescription":"TI INA199A2RSWT current sense amplifier, ±1.5% accuracy, high/low-side sensing, -0.3V to 26V input, -40°C to 125°C.
