The 400 kHz -3 dB bandwidth supports current-loop bandwidths up to several tens of kHz, adequate for PWM-switched loads at typical switching frequencies below 200 kHz. The 2 V/µs slew rate ensures the output settles within one switching cycle when the shunt voltage steps from zero to full-scale, avoiding measurement lag in fast-overcurrent detection paths. ## Supply rails and temperature range — deployment envelope The 1.8 mA quiescent supply current keeps the thermal budget light in densely populated boards. ## Package and footprint — 8-TSSOP The 90 µA input bias current is typical for a bipolar-input current-sense amplifier; the shunt resistor value should be chosen so that the bias current does not introduce a significant voltage drop error at the sense nodes.","metaTitle":"INA240A2PWR Current-Sense Amplifier, 400 kHz Bandwidth","metaDescription":"Texas Instruments INA240A2PWR zero-drift current-sense amplifier. 2.7 V to 5.5 V supply, 400 kHz bandwidth, 5 µV offset, -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":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Slew Rate":"2V/µs","Output Type":"-","Part Status":"Active","Mounting Type":"Surface Mount","-3db Bandwidth":"400 kHz","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP (0.173\\\", 4.40mm Width)","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":"$3.4900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b914b1df9f950ea14b0535b1205113bf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA240A2PWR/alternatives.json"},"ai":{"faq":[{"question":"Is the INA240A2PWR obsolete?","answer":"No."},{"question":"How does the INA240A2PWR compare to the INA240A1PWR?","answer":"Both are pin-compatible zero-drift current-sense amplifiers in the INA240 family.
