With a 900 kHz bandwidth and a 2 V/µs slew rate, it can track load transients on a switching regulator output or monitor motor current ripple. Supply range runs from 2.7 V to 20 V, covering common 3.3 V, 5 V, and 12 V rails without an extra regulator. The wide temperature range also covers engine-bay electronics and factory-floor sensor interfaces where ambient heat is a given. ## Supply current and input bias — the power budget Quiescent supply current is 370 µA, low enough for battery-powered monitoring loops. Input bias current is 20 µA — typical for a current-sense amplifier with internal gain-setting resistors; it flows through the shunt and adds a small offset, so factor it into the error budget at very low shunt values. ## Package and footprint Housed in an SC-70-5, a 5-pin surface-mount package with 0.65 mm pitch. The same footprint covers the 5-TSSOP and SOT-353 variants listed in the case options. Board space is minimal — roughly 2.0 mm × 2.1 mm — so it fits dense power-management sections.","metaTitle":"INA290A3IDCKR Current Sense Amplifier, 900 kHz, SC-70-5","metaDescription":"Texas Instruments INA290A3IDCKR current sense amplifier: 3 µV offset, 900 kHz bandwidth, 2.7 V to 20 V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"2V/µs","Mounting Type":"Surface Mount","-3db Bandwidth":"900 kHz","Amplifier Type":"Current Sense","Package / Case":"5-TSSOP, SC-70-5, SOT-353","lifecycle_stage":"eol_hot","Current - Supply":"370µA","Number of Circuits":"1","Current - Input Bias":"20 µA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"3 µV","Supplier Device Package":"SC-70-5","Voltage - Supply Span (Max)":"20 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.95","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.95000","currency":"USD"},{"qty":10,"price":"$2.64900","currency":"USD"},{"qty":25,"price":"$2.50440","currency":"USD"},{"qty":100,"price":"$2.17040","currency":"USD"},{"qty":250,"price":"$2.05904","currency":"USD"},{"qty":500,"price":"$1.84758","currency":"USD"},{"qty":1000,"price":"$1.57500","currency":"USD"},{"qty":3000,"price":"$1.57500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8ef3b1b8c3b67c630187bad3db9f54d1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the INA290A3IDCKR obsolete?","answer":"No. It remains available for new designs and production."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA290A3IDCKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA290A3IDCKR when reusing this data.
