Internally it integrates an ADC, comparator, fan speed counter, multiplexer, and register bank — so it can read one or two temperature diodes (internal and external sensor paths), compare against programmed limits, and drive a fan output accordingly over SMBus. The ±1°C temperature accuracy is sufficient for closed-loop fan speed regulation in most server, telecom, and industrial equipment where keeping the airflow matched to the thermal load saves acoustic noise and fan wear. ## Temperature range and where it fits Rated for 0°C to 105°C ambient operation, with the external sensor path covering the same span. ## Lifecycle and sourcing posture The ADM1027ARQZ-REEL carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"ADM1027ARQZ-REEL dBCool Fan Controller, Temp Monitor, ±1°C","metaDescription":"ADM1027ARQZ-REEL dBCool remote thermal controller from Analog Devices.
