ADM708AN

Supervisors Overview

The ADM708AN is a microprocessor supervisory circuit designed for monitoring 5 V power supplies and batteries. It features a precision voltage monitor with a threshold of 4.40 V and an active high reset output. The device includes a debounced manual reset input and operates within a supply voltage range up to 5.5 V. Key electrical parameters include a quiescent current of 190 μA, a reset pulse width of 200 ms, and an operating temperature range from -40°C to +85°C. It is housed in an 8-pin DIP package.

Supervisors Feature Summary

• Precision supply voltage monitoring with guaranteed valid reset signals at low voltages
• Active high reset output configuration for direct interface compatibility
• Debounced manual reset input to prevent false triggering during user interaction

Supervisors Applications

• Microprocessor systems requiring reliable power supervision
• Computers and controllers needing critical supply monitoring
• Intelligent instruments dependent on stable voltage levels

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and pinout compatibility. Confirm end-of-life status and last-time-buy dates prior to procurement planning. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Supervisors Selection Notes

Select this component when an active high reset signal is required for system initialization. Consider the 4.40 V threshold for standard 5 V rail monitoring applications. Evaluate the 190 μA quiescent current for power-sensitive designs. Verify that the manual reset input debounce requirements align with the system's user interface timing constraints.

Supervisors Part Context

The ADM708 belongs to the ADM705/ADM706/ADM707/ADM708 family of low-cost microprocessor supervisory circuits. This series provides essential power management functions including voltage monitoring and reset generation. The family offers variations in reset polarity and watchdog timer inclusion to suit different system architectures.

Supervisors Replacement Considerations

MAX708CPA+ and MAX708EPA+ are documented similar replacements.
