ADM698ARZ

Supervisors Overview

The ADM698ARZ is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a supply voltage range of 4.75 V to 5.5 V and features a threshold voltage of 4.65 V with an overvoltage threshold of 4.73 V. The device provides a push-pull output type and includes a watchdog timer functionality. It has a reset delay time of 200 ms and draws a working supply current of 1.95 mA. The component supports through-hole installation in a PDIP-8 package and functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates watchdog timer functionality for system reliability monitoring
• Provides push-pull output configuration for direct logic interfacing
• Includes internal overvoltage detection capabilities

Supervisors Applications

• CMOS process supervision in industrial control systems
• Voltage monitoring for embedded microcontroller units
• Power management integrity checks in portable electronics

Supervisors Procurement Notes

Verify the specific suffix 'ARZ' against official Analog Devices documentation to confirm package type and RoHS compliance status. Confirm availability status as distribution channels may indicate limited stock or end-of-life conditions. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-supply CMOS supervisor with integrated watchdog timing is required. Compare the 4.65 V threshold against the target system's nominal voltage to ensure proper reset triggering. Evaluate the 200 ms reset delay against the processor startup requirements. Consider the PDIP-8 package constraints if surface-mount alternatives are preferred for high-density layouts.

Supervisors Part Context

The ADM698 belongs to the ADM69x series of supervisory circuits from Analog Devices, which focus on providing reliable power management solutions for digital systems. This series typically integrates essential monitoring functions into compact packages, reducing external component count. The ADM698 specifically targets applications requiring robust voltage supervision with minimal external support components.

Supervisors Replacement Considerations

Consult Analog Devices datasheets for cross-reference candidates such as the ADM697 or ADM695 series. Verify that substitute parts match the 4.65 V threshold, push-pull output type, and watchdog functionality. Ensure package compatibility and thermal performance align with the existing design constraints.
