It talks over I²C or SMBus, so it hangs directly on a microcontroller's two-wire bus without extra glue. The local channel gives 8-bit resolution; the remote channel steps up to 11-bit for finer granularity on distant sensors. Accuracy is ±1.5°C on the local reading and ±3.5°C on the remote side — enough for thermal management in industrial controllers, server racks, or power supplies where you need to track hot spots across a board. ## Supply and temperature range Supply voltage runs from 3V to 3.6V — a clean 3.3V rail is the natural fit. If your rail sags below 3V the part stops working, so watch the regulator tolerance on a shared bus. The operating temperature covers -40°C to 125°C, which puts it in the industrial and under-hood automotive class, not just a bench-top part. The remote sensor input can read a diode as cold as -64°C and as hot as 150°C, which matters if you are monitoring a power transistor case or a motor winding that runs above the controller's own ambient. ## Package and mounting It comes in a 24-lead WFQFN with an exposed pad — 4x4 mm body, surface mount. The exposed pad needs a thermal land on the PCB and a via stitch to a ground plane if you are pulling more than a few mA. No lab bench required for the swap, but the QFN footprint means a hot-air station or reflow oven; not a hand-solder job in the field unless you have a fine-tip iron and steady hands. The shipping medium is Tube, so if your pick-and-place line expects Tape & Reel, order the T&R suffix variant instead. ## Features and compliance The part includes an output switch, programmable temperature limits, and a standby mode — useful for waking up a system only when a threshold is crossed. It is ROHS3 compliant, so no conflict with EU or California RoHS requirements.","metaTitle":"MAX6581TG9E+ Temperature Sensor, I²C/SMBus, ±1.5°C Accuracy","metaDescription":"MAX6581TG9E+ digital temperature sensor from Maxim Integrated.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Features":"Output Switch, Programmable Limit, Standby Mode","Resolution":"8 b (Local), 11 b (Remote)","Output Type":"I²C/SMBus","Sensor Type":"Digital, Local/Remote","Mounting Type":"Surface Mount","Package / Case":"24-WFQFN Exposed Pad","Test Condition":"30°C ~ 85°C (0°C ~ 150°C)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"24-TQFN (4x4)","Accuracy - Highest (Lowest)":"±1.5°C (±3.5°C)","Sensing Temperature - Local":"-40°C ~ 125°C","Sensing Temperature - Remote":"-64°C ~ 150°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.76000","currency":"USD"},{"qty":5,"price":"$5.08200","currency":"USD"},{"qty":10,"price":"$4.48900","currency":"USD"},{"qty":25,"price":"$3.64200","currency":"USD"},{"qty":50,"price":"$3.21860","currency":"USD"},{"qty":100,"price":"$3.13390","currency":"USD"},{"qty":500,"price":"$2.62570","currency":"USD"},{"qty":1000,"price":"$2.45630","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX6581.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX6581TG9E+ RoHS compliant?","answer":"Yes, it is ROHS3 compliant, so it meets the current RoHS directive without exemptions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6581TG9E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6581TG9E when reusing this data.
