ADM8698ANZ

Supervisors Overview

The ADM8698ANZ is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply levels and generate reset signals. It operates within a threshold voltage range of 3 V to 5.5 V, with a maximum power supply voltage of 5.5 V. The device features a push-pull output type and provides a reset delay time of 280 ms. It supports a single monitored input and does not include manual reset, watchdog timer, or battery backup switch functionalities. The component is housed in an 8-pin PDIP package for through-hole installation. It functions within a temperature range of -40°C to +85°C and consumes a working power supply current of 100 uA. The part is classified under PMIC - Power Management ICs.

Supervisors Feature Summary

• Provides voltage supervision with a fixed reset threshold for reliable power monitoring
• Features a push-pull output configuration for direct interface compatibility
• Includes a defined reset delay time to ensure stable system initialization
• Operates without manual reset controls or additional watchdog timers

Supervisors Applications

• Microprocessor power supply monitoring systems
• Embedded controller reset signal generation
• Industrial control unit power supervision
• Consumer electronics power management circuits

Supervisors Procurement Notes

Verify the specific suffix ANZ indicates lead-free compliance and plastic packaging details before ordering. Confirm that the PDIP-8 through-hole package matches the target PCB layout requirements. Check current availability status as distribution channels may list this component as discontinued or limited stock. Ensure the operating temperature range meets the environmental conditions of the final application. Cross-reference the exact part number with official Analog Devices documentation to confirm functional specifications.

Supervisors Selection Notes

Select the ADM8698ANZ when a simple, low-current voltage supervisor is required for systems operating between 3 V and 5.5 V. Choose this part if a push-pull output is necessary for driving logic inputs directly. Consider this component for applications where a fixed reset delay of 280 ms is acceptable for system startup. Evaluate the PDIP-8 package size constraints against available board space. Opt for this device over integrated solutions if standalone supervision with minimal external components is preferred.

Supervisors Part Context

The ADM8698 belongs to the ADM8698 series of supervisory circuits from Analog Devices. It serves as an improved version of earlier models like the ADM698, offering enhanced reliability for power monitoring tasks. The family focuses on providing essential reset functions without complex programmability. This specific variant utilizes a through-hole package, distinguishing it from surface-mount alternatives in the same product line. It remains a standard solution for basic voltage supervision needs in industrial and commercial electronics.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ADM709LARZ, ADM8699ARNZ, MAX705ESA+, and MAX709LESA+. Verify pinout compatibility and threshold voltage alignment when substituting. Ensure the replacement part supports the required through-hole or surface-mount technology based on the existing design.
