ADM1022ARQ Description

Short technical summary and product information.

The ADM1022ARQ from Analog Devices is a versatile temperature monitor and fan controller designed for microprocessor-based systems. It features the capability to measure the temperature of one or two remote sensor diodes, making it suitable for monitoring processor temperatures in single or dual-processor configurations.

 

Key electrical specifications include a supply voltage range of 3.0V to 5.5V and a typical supply current of 1.4mA to 2.6mA. The device offers both on-chip and external diode temperature sensing with resolutions of 1°C. Accuracy for the internal sensor is ±3°C, while the external diode sensor accuracy is ±5°C. It supports a 16-QSOP package and surface mount installation.

 

This ASIC integrates a System Management Bus (SMBus) interface for reading measured values and programming limit comparisons. It also includes a DAC for fan speed control and provides automatic hardware temperature trip points. Brownout detection is also a feature, enhancing system reliability. The ADM1022ARQ is well-suited for applications in network servers, personal computers, and microprocessor-based office equipment.
