This makes it a direct fit for monitoring 12 V, 24 V, 48 V, and even 60 V industrial or automotive power buses without needing a separate supply rail for the amplifier itself. The 150 kHz -3 dB bandwidth covers DC load monitoring, overcurrent detection, and low-speed current loops — it is not intended for switching-regulator feedback or motor phase current sensing where higher bandwidth is required. The 8-SOIC package is a common footprint that fits standard PCB layouts for current-sense applications. ## Supply current and input bias — low burden on the monitored rail Quiescent supply current is 103 µA, and input bias current is 5 µA. Together these mean the sense amplifier itself draws minimal current from the monitored rail, which matters for always-on current monitors in battery-backed systems or where the sense resistor voltage drop must stay small. The 100 µV input offset voltage sets a floor on the minimum measurable shunt voltage — for a 10 mΩ shunt, that offset corresponds to a 10 mA zero-current error, so size the shunt voltage drop accordingly. ## Temperature range and lifecycle — production-ready for harsh environments Rated for -40°C to 125°C, the MAX4081SASA+T covers industrial motor drives, outdoor telecom equipment, and automotive under-hood or chassis-domain applications without a temperature grade exception. The product status is Active, so there is no last-time-buy clock running — this part is orderable through normal distribution for ongoing production and new designs. ROHS3 compliant for EU and global RoHS requirements.","metaTitle":"MAX4081SASA+T Current Sense Amplifier, 150 kHz, 8-SOIC","metaDescription":"MAX4081SASA+T is a 76 V, 150 kHz current sense amplifier in 8-SOIC. -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","-3db Bandwidth":"150 kHz","Amplifier Type":"Current Sense","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"103µA","Number of Circuits":"1","Current - Input Bias":"5 µA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"100 µV","Supplier Device Package":"8-SOIC","Voltage - Supply Span (Max)":"76 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.61","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.61000","currency":"USD"},{"qty":10,"price":"$3.24500","currency":"USD"},{"qty":25,"price":"$3.06800","currency":"USD"},{"qty":100,"price":"$2.65880","currency":"USD"},{"qty":250,"price":"$2.52248","currency":"USD"},{"qty":500,"price":"$2.26340","currency":"USD"},{"qty":1000,"price":"$1.90890","currency":"USD"},{"qty":2500,"price":"$1.81346","currency":"USD"},{"qty":5000,"price":"$1.74528","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/max4080-max4081.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does MAX4081SASA+T compare to MAX4080?","answer":"The MAX4080 is a similar current sense amplifier in the same family but typically offers a lower supply voltage range and different gain options. The MAX4081SASA+T's 76 V maximum supply gives it wider rail headroom for 48 V and 60 V buses where the MAX4080 would exceed its rating. Pin compatibility should be verified per package variant — the 8-SOIC footprint is shared across the family, but gain-setting resistor values differ between versions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX4081SASAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX4081SASAT when reusing this data.
