The 5 µV typical input offset keeps the zero-current error low enough to resolve milliohm shunt drops without calibration. ## Supply current and temperature grade Quiescent supply current is 1.8 mA, which is moderate for a 400 kHz current-sense amp — it stays below the 2 mA mark that would push a 24 V always-on rail into thermal budget trouble.","metaTitle":"TI INA240A2DR Current Sense Amplifier, 400 kHz, 8-SOIC","metaDescription":"TI INA240A2DR current sense amplifier: 400 kHz bandwidth, 1.8 mA supply, -40°C to 125°C, 8-SOIC.","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/INA240A2DR/alternatives.json"},"ai":{"faq":[{"question":"What is the bandwidth of INA240A2DR?","answer":"The -3 dB bandwidth is 400 kHz.
