The rail-to-rail output and 20 kHz bandwidth suit it for DC/DC converter feedback, battery monitoring, and motor-phase current sensing in industrial and automotive environments rated -40°C to 125°C. No separate bias rail is needed — the amplifier runs directly from the same supply as the ADC or microcontroller it feeds, simplifying the power tree. ## 2 µV offset — the spec that sets the shunt value With a 2 µV maximum input offset, the error contribution at a 10 mV full-scale shunt drop is 0.02%. This allows the designer to use a smaller shunt resistor (lower power dissipation) while maintaining measurement accuracy. ## Package and mounting — 10-UQFN (1.8x1.4 mm) Housed in a 10-UFQFN package with a 1.8 mm x 1.4 mm body, this part is intended for space-constrained PCBs. Surface-mount assembly is standard; the small footprint requires careful solder-paste stencil design and a reflow profile suited to the UFQFN land pattern. The supplier device package is 10-UQFN (1.8x1.4).","metaTitle":"TI INA190A5IRSWT Current Sense Amplifier, 20 kHz","metaDescription":"Texas Instruments INA190A5IRSWT zero-drift current sense amplifier. 1.7 V to 5.5 V supply, 2 µV offset, 40 µA supply, -40°C to 125°C. 10-UQFN package.","metaKeywords":null},"attributes":{"series":"Zero-Drift","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"Zero-Drift","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"0.25V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","-3db Bandwidth":"20 kHz","Amplifier Type":"Current Sense","Package / Case":"10-UFQFN","lifecycle_stage":"eol_hot","Current - Supply":"40µA","Number of Circuits":"1","Current - Input Bias":"500 pA","Operating Temperature":"-40°C ~ 125°C (TA)","Gain Bandwidth Product":"27 kHz","Voltage - Input Offset":"2 µV","Supplier Device Package":"10-UQFN (1.8x1.4)","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"1.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.51","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.51000","currency":"USD"},{"qty":10,"price":"$3.14800","currency":"USD"},{"qty":25,"price":"$2.97640","currency":"USD"},{"qty":100,"price":"$2.57960","currency":"USD"},{"qty":250,"price":"$2.44732","currency":"USD"},{"qty":500,"price":"$2.19598","currency":"USD"},{"qty":1250,"price":"$1.87200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f3675670cc497fe5bf22b06f649b6ee9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for INA190A5IRSWT?","answer":"No pin-compatible direct replacement is documented."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA190A5IRSWT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA190A5IRSWT when reusing this data.
