Its 30 kHz bandwidth and ±1.5% accuracy make it a fit for DC motor current monitoring, power-supply load tracking, and battery-management circuits where the shunt voltage is small and the common-mode voltage swings up to 26 V. ## Input range and temperature grade The input common-mode range extends from -0.1 V to 26 V, independent of the supply voltage — so the amplifier can sit on the high side of a 24 V bus and still resolve a 10 mV drop across the shunt without level shifting. Housed in a 10-UFQFN (1.8 mm × 1.4 mm) package, the INA199B2RSWT occupies roughly the footprint of a 0805 resistor — useful when the PCB real estate is tight and the sense amplifier must sit close to the shunt to minimise Kelvin-trace inductance.","metaTitle":"INA199B2RSWT Current Sense Amp, ±1.5%, 30kHz, 10-UQFN","metaDescription":"Texas Instruments INA199B2RSWT Zero-Drift current sense amplifier. ±1.5% accuracy, high/low-side sensing, -0.1V to 26V input, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"Zero-Drift","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"Zero-Drift","Package":"Tape & Reel (TR); Cut Tape (CT)","Accuracy":"±1.5%","Function":"Current Sense","Mounting Type":"Surface Mount","Package / Case":"10-UFQFN","Sensing Method":"High/Low-Side","Voltage - Input":"-0.1V ~ 26V","lifecycle_stage":"eol_hot","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"10-UQFN (1.8x1.4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.35","priceTiers":[{"qty":1,"price":"$1.35000","currency":"USD"},{"qty":10,"price":"$1.20700","currency":"USD"},{"qty":25,"price":"$1.14560","currency":"USD"},{"qty":100,"price":"$0.94110","currency":"USD"},{"qty":250,"price":"$0.87968","currency":"USD"},{"qty":500,"price":"$0.77740","currency":"USD"},{"qty":1250,"price":"$0.61374","currency":"USD"},{"qty":2500,"price":"$0.57900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a65922d962e6c5f616f03cac28898efc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA199B2RSWT/alternatives.json"},"ai":{"faq":[{"question":"What is the INA199B2RSWT used for?","answer":"It is a current-sense amplifier that measures the voltage drop across a shunt resistor to determine load current. It works on the high side or low side of the supply rail, making it suitable for power-monitoring circuits, motor-drive feedback, and battery-charge/discharge tracking in industrial and automotive systems."},{"question":"How does the INA199B2RSWT compare to the INA199B2QDCKRQ1?","answer":"Both are current-sense amplifiers with the same ±1.5% accuracy and high/low-side sensing. The INA199B2QDCKRQ1 is the automotive-qualified (AEC-Q100) version in a different package. The INA199B2RSWT is not automotive-grade, so for non-automotive designs the two are functionally interchangeable, but the package and pinout differ — confirm the PCB footprint before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA199B2RSWT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA199B2RSWT when reusing this data.
