That 76 V maximum supply span is the headline number that decides where this part fits. It means the LMP8481MME-H/NOPB can sense current on a 48 V telecom bus with margin, or on a 60 V industrial drive rail, without needing an external regulator or zener clamp. The 4.5 V minimum means it also works on a 5 V logic rail — but not on a 3.3 V system. If your design runs on 3.3 V or lower, you need a different current-sense amp with a lower minimum supply. The wide range also simplifies BOM consolidation: one part number covers 12 V, 24 V, and 48 V variants across a product family. The ROHS3 compliance keeps it usable for EU and RoHS-regulated markets without an exemption hunt. For a BOM line, you're looking at standard lead times through distribution — no premium for last-time-buy, no broker vetting needed.","metaTitle":"LMP8481MME-H/NOPB Current Sense Amplifier, 4.5-76V, 270kHz","metaDescription":"Texas Instruments LMP8481MME-H/NOPB current sense amplifier, single circuit, 4.5V to 76V supply, 270kHz bandwidth, 80µV offset, 88µA supply, -40°C to 125°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"1V/µs","Mounting Type":"Surface Mount","-3db Bandwidth":"270 kHz","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"88µA","Number of Circuits":"1","Current - Input Bias":"6.3 µA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"80 µV","Supplier Device Package":"8-VSSOP","Voltage - Supply Span (Max)":"76 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.57","priceTiers":[{"qty":1,"price":"$3.57000","currency":"USD"},{"qty":10,"price":"$3.20400","currency":"USD"},{"qty":25,"price":"$3.02880","currency":"USD"},{"qty":100,"price":"$2.62510","currency":"USD"},{"qty":250,"price":"$2.49048","currency":"USD"},{"qty":500,"price":"$2.23470","currency":"USD"},{"qty":1250,"price":"$1.90500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/17e48dc1b8c1dd1881fcd1dbb361125f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMP8481MME-H%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What are alternatives or equivalents to LMP8481MME-H/NOPB?","answer":"The THS4215DRBT is a different class of part — a 350 MHz voltage-feedback op-amp, not a current-sense amplifier — so it is not a functional replacement.
