Input offset voltage is 5 µV typ, which keeps the measurement error negligible when sensing across a 10 mΩ shunt at a 1 A load — the offset contributes just 0.05% error on a 10 mV drop. Quiescent current is 1.8 mA, light enough for always-on sensing in battery-powered equipment. ## Package and temperature — rework-friendly and thermally capable The part is surface-mount, so it needs a solder profile, not a socket.","metaTitle":"TI INA240A4DR Current Sense Amplifier, 400 kHz, 8-SOIC","metaDescription":"Texas Instruments INA240A4DR current sense amplifier: 400 kHz bandwidth, 2 V/µs slew rate, 5 µV offset, 2.7-5.5 V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"2V/µs","Output Type":"-","Mounting Type":"Surface Mount","-3db Bandwidth":"400 kHz","Amplifier Type":"Current Sense","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"1.8mA","Number of Circuits":"1","Base Product Number":"INA240","Current - Input Bias":"90 µA","Operating Temperature":"-40°C~125°C","Voltage - Input Offset":"5 µV","Supplier Device Package":"8-SOIC","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b914b1df9f950ea14b0535b1205113bf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA240A4DR/alternatives.json"},"ai":{"faq":[{"question":"What is the INA240A4DR bandwidth?","answer":"The -3 dB bandwidth is 400 kHz, suitable for DC and low-frequency AC current sensing but not for capturing fast switching transients."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA240A4DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA240A4DR when reusing this data.
