ADM708RARZ

Supervisors Overview

The ADM708RARZ is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single input voltage. It operates within a supply voltage range of 4.75 V to 5.5 V and features a threshold voltage of 4.4 V with an overvoltage threshold of 4.5 V. The device provides a push-pull output, supports manual reset functionality, and includes power-fail detection without a watchdog timer. It has a reset delay time of 200 ms and consumes 250 uA of operating current. The component is housed in an SOIC-8 package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides voltage supervision with manual reset capability for system control
• Includes power-fail detection to identify abnormal supply conditions
• Features push-pull output driver for robust signal transmission

Supervisors Applications

• Microprocessor reset generation in embedded systems
• Power supply monitoring for industrial control units
• Voltage supervision in portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm availability status as some distributors list this part as obsolete or limited supply. Ensure the SOIC-8 package matches your PCB footprint requirements. Check RoHS compliance documentation for regulatory adherence. Validate that the 4.4 V threshold aligns with your system's voltage levels.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold is required for 5 V systems. Consider the SOIC-8 package for surface-mount assembly constraints. Evaluate the 250 uA quiescent current against battery life requirements. Verify that manual reset support meets your system's recovery logic needs. Compare power-fail detection capabilities with alternative supervisors if fault logging is critical.
