ADM8690ANZ

Supervisors Overview

The ADM8690ANZ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5 V to 5.5 V and features a fixed reset threshold voltage of 4.65 V. The device provides a push-pull active-low output with a typical reset delay time of 50 ms. It includes an integrated watchdog timer and battery backup switch functionality. The component is housed in an 8-pin PDIP package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer for system monitoring
• Battery backup switch capability
• Fixed 4.65 V reset threshold voltage
• Push-pull active-low reset output

Supervisors Applications

• Microprocessor power supply management
• Embedded system supervision
• Industrial control circuits

Supervisors Procurement Notes

Verify the specific suffix 'ANZ' confirms lead-free compliance and RoHS standards. Confirm the DIP-8 package type matches the target PCB footprint. Check current availability status as older supervisory components may have limited stock or end-of-life implications. Ensure the 4.65 V threshold aligns with the monitored rail requirements.

Supervisors Selection Notes

Select this component when a fixed high-voltage threshold near 5 V is required for standard logic systems. The integrated watchdog simplifies design compared to discrete solutions. Consider the PDIP package for through-hole assembly needs. Verify that the 50 ms reset delay meets the processor startup timing constraints.

Supervisors Part Context

This part belongs to the ADM869x family of supervisory circuits from Analog Devices. It serves as an improved version of earlier ADM690 series devices, offering enhanced reliability for critical system monitoring applications. The family typically includes variants with different thresholds and packages.

Supervisors Replacement Considerations

Public confirmed substitutes include ADM8691ANZ and ADM8692ANZ. These parts share similar functionality but differ in reset threshold voltages. Verify pin compatibility and electrical specifications before substitution.
