The tighter remote channel (±0.5°C) is the one that matters when you are tracking a processor die or a hot spot on a power stage — a 0.5°C window keeps the fan response from hunting. The local sensor (±1°C) is adequate for ambient or board-temperature monitoring. If your design needs better than ±0.5°C on the remote channel, you step up to a dedicated remote-diode temperature sensor; if you only need ambient monitoring, a simpler SMBus temp sensor without fan control costs less. ## Package and mounting — the 16-QSOP footprint The ADM1031ARQ-REEL is supplied in a 16-QSOP package (3.90 mm body width) for surface-mount assembly. ## Sourcing this part The ADM1031ARQ-REEL is sourced to order through independent distribution. Because the part is Active, there is no urgency to stockpile — but the Bulk shipping medium and RoHS-non-compliant status mean you should confirm the packaging and compliance match your BOM requirements before committing the line.","metaTitle":"ADM1031ARQ-REEL Temp Monitor, Fan Control","metaDescription":"ADI ADM1031ARQ-REEL intelligent temp monitor with fan control. ±1°C local, ±0.5°C remote accuracy.
