ADM708SAR-REEL

Supervisors Overview

The ADM708SAR-REEL is a microprocessor supervisory circuit designed for monitoring 3 V or 3.3 V power supplies. It features a typical reset threshold voltage of 2.93 V with a maximum operating supply voltage of 5.5 V and minimum of 1 V. The device provides active high and active low push-pull outputs, a debounced manual reset input, and a 200 ms reset pulse width. It operates within an industrial temperature range of -40°C to +85°C and consumes a maximum quiescent current of 100 μA.

Supervisors Feature Summary

• Provides precision voltage monitoring with independent active high and active low outputs
• Includes a debounced manual reset input for system control
• Ensures valid reset signals at supply voltages as low as 1 V

Supervisors Applications

• Microprocessor systems requiring reliable power supervision
• Portable instruments and battery-operated devices
• Controllers and intelligent instruments

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the component meets all environmental and electrical requirements for the intended application before procurement.

Supervisors Selection Notes

Select this component when dual polarity output options are required for flexible interface compatibility with various logic families. Consider the 2.93 V threshold specifically for 3 V or 3.3 V rail monitoring applications. Evaluate the 100 μA quiescent current against system power budget constraints to ensure efficiency in portable designs.

Supervisors Part Context

This part belongs to the ADM706/ADM708 series of microprocessor supervisory circuits from Analog Devices. It serves as a successor to the MAX706/MAX708 series, offering improved performance and reliability for critical monitoring tasks in industrial and commercial electronics environments.

Supervisors Replacement Considerations

The ADM708SARZ is a verified equivalent variant with identical electrical characteristics but in a tube package instead of a reel. Verify pinout compatibility and thermal performance when substituting between reel and tube packaging formats.
