For a 12 V/µs edge on the shunt voltage, the amplifier slews at its limit, so budget settling time if the signal chain includes a fast ADC. The 8-TSSOP is a common pinout for current-sense amplifiers, so board layout reuse across alternate suppliers is straightforward.","metaTitle":"INA240A1PWR Current-Sense Amplifier, 400 kHz, 2 V/µs","metaDescription":"TI INA240A1PWR current-sense amplifier: 5 µV offset, 400 kHz bandwidth, 2 V/µs slew rate, -40 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-TSSOP (0.173\\\", 4.40mm 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-TSSOP","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/INA240A1PWR/alternatives.json"},"ai":{"faq":[{"question":"What is the gain of INA240A1PWR?","answer":"The INA240A1PWR is a fixed-gain current-sense amplifier; its gain is set internally by the device variant.

No external gain-setting resistors are needed."},{"question":"Does INA240A1PWR work with a 5 V supply?","answer":"Yes."},{"question":"Is INA240A1PWR compatible with 3.3 V logic?","answer":"Yes. With a minimum supply of 2.7 V, the INA240A1PWR can run from a 3.3 V rail. Its output voltage swings within the supply rails, so it interfaces directly with 3.3 V logic inputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA240A1PWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA240A1PWR when reusing this data.
