ADM825ZYKSZ-R7

Supervisors Overview

The ADM825ZYKSZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring voltage levels in electronic systems. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 3.08 V with an overvoltage threshold of 3.11 V. The device provides a push-pull output and includes manual reset functionality without a watchdog timer or battery backup switch. It exhibits a reset delay time of 280 ms and maintains an accuracy of 2.5%. The component supports operation across a temperature range from -40 °C to +125 °C, drawing a typical operating supply current of 24 uA.

Supervisors Feature Summary

• Industrial control system reset circuits

Supervisors Procurement Notes

Verify the specific suffix ZYKSZ against official Analog Devices documentation to confirm pinout and package configuration. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the reel packaging matches production requirements. Cross-reference the manufacturer part number with the latest datasheet revision to validate electrical characteristics before integration into design specifications.

Supervisors Selection Notes

Select this component when a supervisory circuit with manual reset is required for low-power applications. The push-pull output allows direct interfacing with logic inputs without additional pull-up resistors. Consider the 24 uA quiescent current for battery-sensitive designs. Verify that the 3.08 V threshold aligns with the monitored rail's minimum operating voltage. Ensure the SC-70-5 package fits the available PCB footprint constraints.

Supervisors Part Context

This part belongs to the ADM825 series of microprocessor supervisors from Analog Devices. These devices are engineered to provide reliable reset signals for digital systems under varying power conditions. The series typically offers various threshold options and package styles to accommodate different design needs while maintaining high accuracy and low power consumption standards.

Supervisors Replacement Considerations

Check Analog Devices documentation for direct replacements within the ADM825 family. Verify functional compatibility regarding threshold voltages and output types. Ensure pin-to-pin compatibility if physical substitution is required.
