That topology is what holds the input offset voltage to 5 µV — a figure that keeps the measurement error negligible even when the shunt resistor drops only a few millivolts at low load current. The part is qualified to AEC-Q100, so it carries the temperature and reliability screening expected for under-hood and chassis-domain electronics. ## 400 kHz bandwidth — what it resolves and what it doesn't The -3 dB bandwidth is 400 kHz, with a slew rate of 2 V/µs. That is fast enough to capture the current waveform in a motor-drive PWM cycle at typical carrier frequencies (4–20 kHz) and to track solenoid or relay coil current. It will not resolve the sub-microsecond edges of a GaN or SiC switching stage — for those you need a wider-bandwidth current sense amp. Supply current is 1.8 mA, which is moderate for a precision sense amp. No special pad geometry or thermal vias are needed — the sense resistor and the amplifier sit on the same copper pour for Kelvin sensing. The BOM line can be committed without a phase-out risk, and standard lead times apply through the distribution channel.","metaTitle":"INA240A3EDRQ1 Current Sense Amplifier, AEC-Q100, 400 kHz","metaDescription":"TI INA240A3EDRQ1 automotive zero-drift current sense amplifier, 2.7 V to 5.5 V supply, 400 kHz bandwidth, 5 µV offset, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100, Zero-Drift","Package":"Bulk","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","Current - Input Bias":"90 µA","Operating Temperature":"-40°C~150°C(TA)","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":"$1.0000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/feaae65a40f0dee3268ea1043bbbfbf6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA240A3EDRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is INA240A3EDRQ1 automotive qualified?","answer":"Yes.
