The spec covers the full -40°C to 120°C range. ## SMBus interface and fan control integration The SMBus output lets the ADT7467ARQ talk directly to a system management controller (like a BMC or EC) without glue logic. The internal register bank stores temperature readings and fan-speed setpoints, so the host can poll the part periodically rather than continuously. The fan output is a PWM or linear drive signal — the topology includes a comparator and fan speed counter, meaning closed-loop speed control is handled on-chip, not in firmware. That saves a few lines of code and offloads the host MCU. ## Lifecycle and compliance reality The catch is RoHS compliance: this part is marked RoHS non-compliant. That means it contains lead (Pb) in the solder finish or die-attach material, which excludes it from EU RoHS-regulated consumer products unless an exemption applies. For industrial, telecom, or military applications that are exempt from RoHS, or for legacy BOMs that already use leaded solder, the non-compliant status is irrelevant. If your compliance team requires RoHS, look at the ADT7468ARQZ-RL7 which carries a -Z suffix indicating RoHS-compliant plating, though its accuracy is ±2°C max instead of ±1.5°C.","metaTitle":"ADT7467ARQ dBCool Fan Control, Temp Monitor, ±1.5°C Accuracy","metaDescription":"ADI ADT7467ARQ dBCool fan controller and temperature monitor with ±1.5°C accuracy, SMBus output, -40°C to 120°C range.
