ADM1023ARQ

Overview

The ADM1023ARQ is a microprocessor system thermal monitor manufactured by Analog Devices Inc. It integrates two digital temperature sensors and an analog output channel within a single integrated circuit. The device operates on a supply voltage ranging from 3 V to 5.5 V and communicates via a two-wire serial interface compatible with SMBus standards. It provides programmable overtemperature and undertemperature limits with an ALERT output for system management. The component is housed in a small 16-lead QSOP package, designed for efficient space-constrained applications.

Feature Summary

• Integrates dual digital temperature sensing channels for precise thermal monitoring
• Includes an additional analog output channel for supplementary measurement capabilities
• Features programmable overtemperature and undertemperature alarm thresholds
• Supports standard two-wire serial communication protocols for system integration

Applications

• Microprocessor-based system thermal management
• Desktop computer motherboard monitoring
• Notebook computer thermal regulation
