ADM8698AN

Supervisors Overview

The ADM8698AN is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor system power integrity. It operates within a supply voltage range of 3 V to 5.5 V and features a push-pull output type for robust signal driving. The device provides a fixed reset delay time of 280 ms to ensure stable power-up sequences. It supports a maximum power dissipation of 500 mW and functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in a PDIP-8 package, suitable for through-hole mounting applications requiring simple reset generation without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides automated power supply monitoring with a fixed reset delay for reliable system initialization
• Features a push-pull output stage capable of driving downstream logic circuits directly
• Operates within a wide input voltage window ranging from 3 V to 5.5 V
• Designed for through-hole integration using a standard PDIP-8 package

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-powered systems requiring low standby current
• Industrial control boards needing extended temperature operation
• Consumer electronics with simple reset requirements

Supervisors Procurement Notes

Verify the specific suffix designation carefully, as the ADM8698AN may be discontinued or superseded by newer variants such as the ADM8698ANZ. Confirm RoHS compliance status and lead times with authorized distributors, as availability varies significantly across regions. Ensure the PDIP-8 package matches your PCB footprint requirements before ordering. Cross-reference part numbers to identify functional equivalents if original stock is unavailable.

Supervisors Selection Notes

Select this component when a simple, cost-effective voltage supervisor is required for single-channel monitoring. It is appropriate for designs where a fixed 280 ms reset delay meets timing constraints. Consider the PDIP-8 package constraint for through-hole assembly processes. Evaluate the 100 uA operating current against system power budgets. Verify that the 5.5 V maximum rating aligns with the highest expected supply voltage under all operating conditions.

Supervisors Part Context

The ADM8698AN belongs to the ADM8698 series of supervisory circuits from Analog Devices. This family focuses on providing essential power management functions for embedded systems. The component serves as an improved version of earlier models like the ADM698, offering enhanced reliability and performance characteristics. It is categorized under PMIC - Power Management ICs, specifically within the Voltage Supervisory subcategory.

Supervisors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the ADM709LARZ, ADM8699ARNZ, MAX705ESA+, and MAX709LESA+. These alternatives offer similar supervisory functions but may differ in package type, threshold voltage, or reset delay specifications. Verify electrical compatibility before substitution.
