That 76 V ceiling covers 48 V telecom buses, 24 V industrial rails with headroom for transients, and 12 V automotive systems — all without an external regulator or level shifter on the sense input. It draws just 75 µA of supply current, so the measurement overhead on the rail is negligible — useful in battery-monitoring or always-on sense paths where every microamp counts. ## Bandwidth, offset, and bias — the bench-level view The 250 kHz -3 dB bandwidth sets the upper frequency for accurate current measurement. For a switching regulator running at a few hundred kHz, the output ripple current is captured; for a DC motor load, the bandwidth is more than enough to track the average current and the start-up surge. The offset contributes a DC error at the output that scales with the sense resistor value — a 10 mΩ shunt gives 10 mV/A, so 100 µV of offset translates to 10 mA of zero-current error. The 5 µA bias flows through the sense resistor and adds a small offset; for a 10 mΩ shunt that is 50 µV, negligible next to the offset term. ## Package, temperature grade, and where it fits on the board The part comes in an 8-uMAX/uSOP package, the same footprint as an 8-MSOP or 8-TSSOP — 3.00 mm wide, 0.118-inch pitch. Surface-mount only; the small body fits on a 2-layer board without trouble, and the exposed pad (if present on the variant) helps pull heat into the ground plane. The supply current stays at 75 µA across the range, though the offset voltage drifts with temperature — the datasheet's drift spec is the number to check for precision applications.","metaTitle":"MAX4080TAUA+T Current Sense Amplifier, 250 kHz, 8-uMAX","metaDescription":"MAX4080TAUA+T high-side current sense amplifier from Analog Devices. 76V max supply, 75µA supply current, 250 kHz bandwidth, 8-uMAX package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","-3db Bandwidth":"250 kHz","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"75µA","Number of Circuits":"1","Current - Input Bias":"5 µA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"100 µV","Supplier Device Package":"8-uMAX/uSOP","Voltage - Supply Span (Max)":"76 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.30000","currency":"USD"},{"qty":10,"price":"$2.96400","currency":"USD"},{"qty":25,"price":"$2.80200","currency":"USD"},{"qty":100,"price":"$2.42840","currency":"USD"},{"qty":250,"price":"$2.30388","currency":"USD"},{"qty":500,"price":"$2.06728","currency":"USD"},{"qty":1000,"price":"$1.74349","currency":"USD"},{"qty":2500,"price":"$1.65632","currency":"USD"},{"qty":5000,"price":"$1.59405","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9a338f76db050a41eb0b4026ac7c5cd4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the MAX4080TAUA+T used for?","answer":"It is a high-side current sense amplifier — it measures the voltage drop across a shunt resistor on the supply rail and outputs a proportional voltage.
