The 2.7 V to 20 V supply span lets it run off common rails from 3.3 V logic supplies up to 24 V industrial buses without an extra regulator. ## What the 3 µV offset and 680 µA supply mean for your BOM A 3 µV input offset lets the INA2290A2IDGKR resolve tens of milliamps through a 1 mΩ shunt, which keeps shunt power dissipation low and board area small. The 680 µA supply current is low enough for always-on current monitoring in battery-powered equipment — a 24/7 IoT node drawing 680 µA from the sense amplifier alone is acceptable in a system with a 500 mAh battery. The 2 V/µs slew rate means the output settles within a few microseconds after a current step, fast enough for cycle-by-cycle overcurrent limiting in a 100 kHz switching regulator. ## Package and mounting: 8-VSSOP with Tape & Reel options Surface-mount assembly with standard reflow profiles applies; MSL level should be verified from the latest TI packaging data. There is no announced last-time-buy or end-of-life notice, making it suitable for design-in on new production builds. ROHS3 compliance is confirmed, so it meets EU and global material restrictions without exemption tracking.","metaTitle":"TI INA2290A2IDGKR Current Sense Amplifier, 1.1 MHz, 8-VSSOP","metaDescription":"TI INA2290A2IDGKR current sense amplifier: 2V/µs slew rate, 3 µV offset, 680 µA 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":"2V/µs","Mounting Type":"Surface Mount","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"680µA","Number of Circuits":"1","Current - Input Bias":"20 µA","Operating Temperature":"-40°C ~ 125°C (TA)","Gain Bandwidth Product":"1.1 MHz","Voltage - Input Offset":"3 µV","Supplier Device Package":"8-VSSOP","Voltage - Supply Span (Max)":"20 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.31","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.31000","currency":"USD"},{"qty":10,"price":"$4.76800","currency":"USD"},{"qty":25,"price":"$4.50760","currency":"USD"},{"qty":100,"price":"$3.90660","currency":"USD"},{"qty":250,"price":"$3.70628","currency":"USD"},{"qty":500,"price":"$3.32564","currency":"USD"},{"qty":1000,"price":"$2.83500","currency":"USD"},{"qty":2500,"price":"$2.83500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8ef3b1b8c3b67c630187bad3db9f54d1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives or equivalents to INA2290A2IDGKR?","answer":"The closest functional alternative within the same family is the INA4290A2IRGVR, a quad-channel version of the same current sense amplifier core.
