Supervisors Procurement Notes

Verify component status as the ADM693AR-REEL is listed as obsolete and no longer manufactured by Analog Devices. Confirm availability of direct substitutes such as the ADM693ARZ-REEL before procurement planning. Ensure compatibility with existing design specifications when selecting replacement parts from authorized distributors.

Supervisors Selection Notes

Select this component for applications requiring precise 5V CMOS process supervision with integrated watchdog and backup functions. Consider the SOIC-16 package constraints and thermal dissipation limits of 600 mW. Evaluate the 100 µA standby current against system power budgets. Verify that the open-drain output interface matches the target controller requirements.
