With a sensing and operating temperature range of -40°C to 125°C, this part is suited for equipment enclosures, server racks, telecom base stations, and industrial control panels where both ambient and hot-spot junction temperatures need regulation. ## ±1°C accuracy and dual-sensor topology Temperature measurement accuracy is rated at ±1°C, which is tight enough for most fan-speed control loops and overtemperature alarm thresholds without requiring external calibration. The internal sensor monitors the local PCB ambient near the IC, while the external sensor input connects to a remote diode (typically a CPU, GPU, or power transistor) for junction-temperature tracking. An output alarm pin asserts when a programmed temperature limit is exceeded, providing a hardware interrupt for system shutdown or fan boost without polling the SMBus. ## Supply voltage and interface All configuration and temperature readback occurs over the SMBus, which is a subset of I²C with timeout and alert-line support, making it straightforward to integrate with most microcontrollers and baseboard management controllers. ## Package and ordering code The ADM1034ARQ-REEL7 is supplied in a 16-lead SSOP package with a 3.90 mm body width (0.154\"), also referred to as a 16-QSOP in the supplier device package field. ## Lifecycle and compliance The ADM1034ARQ-REEL7 is listed as Active in production status, meaning it remains in current manufacture with no announced end-of-life plan. This part is RoHS non-compliant, which is a constraint for designs that must meet EU RoHS or similar lead-free directives. Verify your exemption status or consider the ADM1034ARQ base part if your process allows lead-bearing solder.","metaTitle":"ADM1034ARQ-REEL7 Thermal Monitor, ±1°C, SMBus, 16-SSOP","metaDescription":"ADI ADM1034ARQ-REEL7 thermal monitor and fan controller, ±1°C accuracy, SMBus output, internal/external sensor, -40°C to 125°C, 16-SSOP.","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":"Fan Control, Temp Monitor","Topology":"ADC, Comparator, Multiplexer, Register Bank","Output Fan":"Yes","Output Type":"SMBus","Sensor Type":"Internal and External","Output Alarm":"Yes","Mounting Type":"Surface Mount","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Sensing Temperature":"-40°C ~ 125°C, External Sensor","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"16-QSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.29","stockQuantity":0,"priceTiers":[{"qty":57,"price":"$5.29000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8144b2b195837c5cda9bda75b1071bd7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the accuracy of ADM1034ARQ-REEL7?","answer":"The accuracy is ±1°C, covering both the internal and external sensor channels over the full -40°C to 125°C temperature range."},{"question":"Does ADM1034ARQ-REEL7 support external temperature sensors?","answer":"Yes, it supports one external diode-connected transistor (typically a 2N3904 or substrate PNP) in addition to its internal sensor, allowing remote junction temperature monitoring."},{"question":"What is the difference between ADM1034ARQ and ADM1034ARQ-REEL7?","answer":"The ADM1034ARQ-REEL7 is the tape-and-reel packaged variant of the ADM1034ARQ base part.
