It integrates precision gain-setting resistors and a wide input common-mode range that extends from the negative supply to the positive rail, making it suitable for 5 V, 12 V, and 24 V systems. The supply span from 2.7 V to 20 V covers 3.3 V logic rails, 5 V analog supplies, and 12 V/24 V industrial buses without an external regulator. ## Input offset and bias — what they mean for measurement accuracy The 15 µV input offset voltage is low enough that with a 10 mΩ shunt carrying 1 A, the offset contributes only 0.15% error before calibration. The 20 µA input bias current flows through the shunt and can introduce a small voltage drop — negligible with a 10 mΩ shunt (200 µV), but worth accounting for if the shunt resistance is higher. For a 100 mΩ shunt the bias drop becomes 2 mV, which may need a system-level trim.","metaTitle":"TI INA293B2IDBVT Current Sense Amplifier, 1.3 MHz, SOT-23-5","metaDescription":"Texas Instruments INA293B2IDBVT current sense amplifier: 2.5 V/µs slew rate, 1.3 MHz bandwidth, 15 µV offset, 2.7 V to 20 V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"2.5V/µs","Mounting Type":"Surface Mount","-3db Bandwidth":"1.3 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","Voltage - Input Offset":"15 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":"$3.72","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.72000","currency":"USD"},{"qty":10,"price":"$3.34000","currency":"USD"},{"qty":25,"price":"$3.15760","currency":"USD"},{"qty":100,"price":"$2.73670","currency":"USD"},{"qty":250,"price":"$2.59636","currency":"USD"},{"qty":500,"price":"$2.32972","currency":"USD"},{"qty":1250,"price":"$1.98600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5d12be184aa0615f4bd161ad1cc138e2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the gain of INA293B2IDBVT?","answer":"The gain is not explicitly listed in the available specifications.

The INA4290A2IRGVR has a slightly lower bandwidth (1.1 MHz) and a lower input offset voltage (6 µV). For a single-channel replacement with similar bandwidth, the INA254A1IPWAR (350 kHz, zero-drift topology) is another option, though its bandwidth is significantly lower. Neither is a direct pin-compatible drop-in; board layout and gain configuration must be verified."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA293B2IDBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA293B2IDBVT when reusing this data.
