ADM698ANZ

Supervisors Overview

The ADM698ANZ is a CMOS supervisory circuit manufactured by Analog Devices Inc., designed to monitor voltage levels in electronic systems. It operates within a supply voltage range up 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 built-in watchdog timer for system reliability. It has a reset delay time of 200 ms and consumes 1.95 mA of operating current. The component is housed in a PDIP-8 package, supports through-hole mounting, and functions reliably across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system recovery without manual reset requirements
• Provides precise voltage supervision with defined threshold and overvoltage detection levels
• Features a push-pull output stage for direct interface with digital logic circuits

Supervisors Applications

• Embedded systems requiring automatic power-on reset and watchdog functionality
• Industrial control units needing reliable voltage monitoring under varying thermal conditions
• Consumer electronics utilizing CMOS logic that require supervised power sequencing

Supervisors Procurement Notes

Verify the specific suffix ANZ indicates the PDIP-8 through-hole package variant when sourcing. Confirm availability status as distribution channels may list limited stock or end-of-life constraints. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range to maintain parameter accuracy. Cross-reference pinouts with official datasheets to prevent integration errors during PCB design.

Supervisors Selection Notes

Select this component when a single-supply CMOS supervisor with integrated watchdog capability is required. It is suitable for designs needing a fixed 4.65 V threshold rather than adjustable options. Consider the PDIP-8 package if through-hole assembly is mandated. Evaluate the 1.95 mA quiescent current against battery life requirements if applicable. Compare against other ADM series parts if manual reset or different output types are needed.

Supervisors Part Context

The ADM698 belongs to the ADM698 series of supervisory circuits from Analog Devices. It is part of the broader PMIC category, specifically focusing on voltage supervision and system protection. This series typically addresses the need for reliable power management in microprocessor-based systems, ensuring stable operation through monitored reset signals and watchdog timers.
