With a -0.1 V to 26 V input common-mode range, it handles a 12 V automotive rail, a 24 V industrial bus, or a 5 V logic rail without external level translation — the shunt can sit on either side of the load. The ±1 % accuracy figure is the total output error over the full temperature range, not just at 25 °C. ## Footprint and board integration The 10-UQFN package measures 1.8 mm x 1.4 mm with a 0.40 mm pitch — the land pattern fits under a microcontroller or between passives on a dense mixed-signal board. The supplier device package is the same 10-UQFN (1.8x1.4), so the stencil and footprint match the datasheet recommendation. Surface-mount assembly on standard FR-4 with a lead-free reflow profile is straightforward; the package is MSL-1 per the TI shipping label, so no moisture-sensitive bake is required before reflow. ## Active lifecycle and compliance posture ROHS3 Compliant certification covers the full substance restriction list without exemptions, so the part meets EU RoHS and UK REACH requirements without a compliance gap.","metaTitle":"TI INA199C2RSWT Current Sense IC, ±1% Accuracy, 10-UQFN","metaDescription":"INA199C2RSWT current-sense amplifier from Texas Instruments, ±1% accuracy, high/low-side sensing, -0.1V to 26V input range, -40°C to 125°C temp range, 10-UQFN","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Accuracy":"±1%","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":"$1.67","priceTiers":[{"qty":1,"price":"$1.67000","currency":"USD"},{"qty":10,"price":"$1.49200","currency":"USD"},{"qty":25,"price":"$1.41560","currency":"USD"},{"qty":100,"price":"$1.16290","currency":"USD"},{"qty":250,"price":"$1.08708","currency":"USD"},{"qty":500,"price":"$0.96068","currency":"USD"},{"qty":1250,"price":"$0.75843","currency":"USD"},{"qty":2500,"price":"$0.71550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a65922d962e6c5f616f03cac28898efc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA199C2RSWT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy INA199C2RSWT and how do I get a price?","answer":"The INA199C2RSWT is available to order through independent distribution channels.
