The ±1°C local figure is tight enough for system-level thermal management in servers and telecom equipment; the ±3°C remote tolerance is typical for tracking a processor junction without a dedicated thermocouple. The internal topology combines an ADC, comparator, multiplexer, and register bank — no external ADC or comparator is needed. The SMBus output reports both temperature readings directly to the host controller. ## Supply voltage and interface The SMBus interface runs at the same supply voltage, so no level shifting is required when connecting to a 3.3V or 5V host bus. An output alarm pin (ALERT) is provided for overtemperature interrupts — the host can be configured to respond to a threshold crossing without polling the SMBus continuously. Supplied in a 16-lead SSOP (3.90 mm width) and also specified with a 16-QSOP supplier device package. Both are surface-mount, fine-pitch packages suitable for compact PCB layouts. ## RoHS and compliance note Marked as RoHS non-compliant. For designs requiring RoHS-10 or REACH compliance, verify the date code and request the latest compliance documentation from the supplier at RFQ.","metaTitle":"ADM1023ARQ-REEL Temp Sensor, ±1°C Local, ±3°C Remote, SMBus","metaDescription":"Analog Devices ADM1023ARQ-REEL temp monitoring system, ±1°C local ±3°C remote accuracy, SMBus output, 3V-5.5V supply.

The only difference is the packaging suffix (REEL7 vs REEL), which affects tape-and-reel vs bulk delivery. The ADM1023ARQ (without -REEL suffix) is also the same die in bulk packaging. For a lower-accuracy alternative, the ADM1021ARQ-REEL offers ±1°C local but ±5°C remote and a narrower 0°C to 100°C sensing range."},{"question":"Will ADM1023ARQ-REEL drop into a board designed for ADM1023ARQ-REEL7-AD?","answer":"Yes — the ADM1023ARQ-REEL and ADM1023ARQ-REEL7-AD share the same die, same 16-SSOP package, same pinout, and same electrical specifications. The only difference is the packaging format: REEL7 indicates tape-and-reel, while REEL indicates bulk (tubes/trays).
