Together they allow the amplifier to resolve millivolt-level drops across a sense resistor — the kind of signal you see when monitoring a 10 mΩ shunt carrying a few hundred milliamps. The 1.5 mA supply current is modest enough to keep the thermal budget in check on a densely populated automotive ECU. ## Package and mounting Supplied in a SOT-23-5 package (SC-74A, SOT-753), surface-mount only. The five-pin footprint is common across many TI current-sense amplifiers, so a layout designed for one variant often accepts the INA293B3QDBVRQ1 without a board spin. Product status is Active, with ROHS3 compliance.","metaTitle":"TI INA293B3QDBVRQ1 Current Sense Amplifier, AEC-Q100, 1 MHz","metaDescription":"TI INA293B3QDBVRQ1 automotive current sense amplifier, AEC-Q100, 1 MHz bandwidth, 2.5 V/µs slew rate, 10 µV offset, SOT-23-5.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"2.5V/µs","Mounting Type":"Surface Mount","-3db Bandwidth":"1 MHz","Amplifier Type":"Current Sense","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Current - Supply":"1.5mA","Number of Circuits":"1","Current - Input Bias":"20 µA","Operating Temperature":"-40°C ~ 125°C (TA)","Voltage - Input Offset":"10 µV","Supplier Device Package":"SOT-23-5","Voltage - Supply Span (Max)":"20 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.66","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.66000","currency":"USD"},{"qty":10,"price":"$3.28500","currency":"USD"},{"qty":25,"price":"$3.10520","currency":"USD"},{"qty":100,"price":"$2.69120","currency":"USD"},{"qty":250,"price":"$2.55324","currency":"USD"},{"qty":500,"price":"$2.29100","currency":"USD"},{"qty":1000,"price":"$1.95300","currency":"USD"},{"qty":3000,"price":"$1.95300","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3baccdd98af263d18df695039bb91404.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional equivalent to INA293B3QDBVRQ1?","answer":"The INA4290A2IRGVR is a quad-channel current sense amplifier with similar bandwidth (1.1 MHz) and offset (6 µV), but it comes in a different package and draws 1.3 mA per channel. For a single-channel replacement, the INA254A1IPWAR offers a zero-drift architecture with 350 kHz bandwidth and 2.4 V/µs slew rate, though its supply range and package differ. Neither is a direct pin-for-pin substitute — verify the footprint and supply rails before swapping."},{"question":"Can INA293B3QDBVRQ1 be used for high-side current sensing?","answer":"Yes. As a current sense amplifier, it is designed to measure the voltage across a shunt resistor placed between the supply rail and the load (high-side) or between the load and ground (low-side).
