ADM1023ARQZ-REEL

Overview

The ADM1023ARQZ-REEL is a dual precision temperature sensor manufactured by onsemi, housed in a 16-QSOP surface-mount package. It features an SMBus digital output interface and supports both local and remote temperature monitoring configurations. The device operates within a supply voltage range of 3V to 5.5V and maintains an operating temperature range from 0°C to 120°C. Local sensor accuracy is specified at ±1°C, while remote sensor accuracy is ±3°C. This component serves as a system temperature monitor for hardware health management.

Feature Summary

• Dual-channel capability for simultaneous internal and external temperature sensing
• Integrated SMBus serial interface for digital communication and configuration
• High-precision local and remote measurement with dedicated alarm outputs

Applications

• System temperature monitoring in microprocessor-based platforms
• Hardware health management in industrial control systems
• Thermal supervision in telecommunications equipment

Procurement Notes

Verify the current lifecycle status before procurement, as this part may be obsolete or subject to limited availability. Confirm that the 16-QSOP package dimensions match the target PCB footprint. Ensure the design supports the required SMBus protocol timing and voltage levels compatible with the 3V to 5.5V operating range.

Selection Notes

Select this component when dual-zone thermal monitoring is required with high local accuracy. It is suitable for designs needing direct digital integration via SMBus without external ADCs. Consider the 120°C maximum operating temperature for high-heat environments. Verify compatibility with existing system reset and alert logic requirements.

Part Context

This device belongs to the ADM102x series of board-mount temperature sensors. It represents an evolution in thermal management ICs designed for comprehensive system supervision. The series typically integrates multiplexing and register banks for efficient data access. It addresses the need for precise thermal tracking in complex electronic assemblies.

Replacement Considerations

Public documentation identifies the ADM1021AARQZ-R7 as a related predecessor component. Verify pinout compatibility and functional equivalence before substitution. Check if the target application requires specific features unique to the ADM1023 architecture.
