The -3 dB bandwidth of 270 kHz and slew rate of 1 V/µs tell you this is a DC-to-low-frequency monitor, not a fast-switching current loop; it's meant for power-supply output monitoring, motor-phase current sensing, or battery-charge/discharge tracking where the signal changes in the tens of kilohertz range, not megahertz. Input offset voltage of 80 µV and input bias current of 6.3 µA let it resolve small voltage drops across the sense resistor — a 10 mV shunt signal at 100 A gives you a usable output without a huge gain error. ## What the 4.5 V to 76 V supply span means for your rail 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. ## Active lifecycle — no LTB scramble The ROHS3 compliance keeps it usable for EU and RoHS-regulated markets without an exemption hunt. ## Sourcing this part — what to expect 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":["Logic ICs"],"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","stockQuantity":0,"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},"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.
