It delivers ±1°C accuracy across the full -55°C to 125°C operating range, making it suitable for thermal management in avionics, satellite payloads, downhole instrumentation, and other high-reliability environments where the board must survive extreme cold and heat. ## Package and mounting Housed in an 8-SOIC (0.154\", 3.90 mm width) surface-mount package. The 8-pin SOIC footprint is a standard layout shared by many temperature sensors and EEPROMs, so board layout is straightforward. ## Lifecycle and sourcing Marked Active in the lifecycle record — no last-time-buy or obsolescence risk for new designs. RoHS non-compliant per the listing, so verify your assembly-house restrictions if you need lead-free solder.","metaTitle":"ADM1020AR-REEL7 Temperature Monitor, ±1°C, SMBus, 8-SOIC","metaDescription":"ADI ADM1020AR-REEL7 system temperature monitor, ±1°C accuracy, SMBus output, internal/external sensor, 3V-5.5V, -55°C to 125°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Bulk","Accuracy":"±1°C","Function":"Temperature Monitor","Topology":"ADC","Output Fan":"No","Output Type":"SMBus","Sensor Type":"Internal and External","Output Alarm":"Yes","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Operating Temperature":"-55°C ~ 125°C","Supplier Device Package":"8-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.84","stockQuantity":0,"priceTiers":[{"qty":357,"price":"$0.84000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3b4dbe068a3032311c8376eb985bbfbe.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the accuracy of ADM1020AR-REEL7?","answer":"The ADM1020AR-REEL7 specifies ±1°C accuracy. This applies across the full -55°C to 125°C operating range for the internal sensor; the external diode channel accuracy depends on the diode ideality factor and layout parasitics."},{"question":"Does ADM1020AR-REEL7 work with a 3.3V supply?","answer":"Yes, the supply range is 3V to 5.5V, so a 3.3V rail is well within spec.
