ADM708ANZ

Supervisors Overview

The ADM708ANZ is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single power supply rail. It operates within a supply voltage range of 4.75 V to 5.5 V and features a reset threshold voltage of 4.4 V with an overvoltage threshold of 4.5 V. The device provides a push-pull output capable of active high or active low configuration, with a manual reset input for user-initiated control. It includes power-fail detection and exhibits a typical reset delay time of 160 ms. The component is housed in an 8-PDIP package and supports through-hole mounting.

Supervisors Feature Summary

• Provides reliable system reset generation upon detection of under-voltage or power-fail conditions
• Features configurable push-pull output drivers supporting both active high and active low logic states
• Includes a manual reset input pin allowing for external user-initiated system resets

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Embedded system reset generation for industrial controllers
• Battery-powered device supervision where stable voltage thresholds are required

Supervisors Procurement Notes

Verify the specific suffix ANZ indicates RoHS compliance and lead-free status per manufacturer documentation. Confirm the 8-PDIP package dimensions match your PCB footprint requirements. Ensure the 4.4 V threshold aligns with your system's nominal 5 V supply tolerance. Check current availability status as distribution channels may vary. Validate that the through-hole installation style suits your assembly process capabilities.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold is appropriate for 5 V systems requiring simple supervision without watchdog functionality. Consider the 8-PDIP package if through-hole mounting is preferred over surface mount alternatives like the ADM708ARZ. Evaluate the 250 uA operating current against system power budget constraints. Verify compatibility with the required active high/low output configuration before finalizing the design.

Supervisors Part Context

The ADM708 series belongs to Analog Devices' family of simple reset supervisor integrated circuits. These devices are engineered to provide essential protection for digital logic by detecting abnormal voltage levels. The ADM708ANZ specifically represents the through-hole variant of this line, offering robust performance in industrial environments. It complements other variants such as the SOIC-8 packaged ADM708ARZ, providing designers with flexible packaging options for different board layout strategies.

Supervisors Replacement Considerations

The ADM708ARZ serves as a direct functional substitute in the SOIC-8 surface-mount package. Cross-reference datasheets to confirm identical electrical parameters, particularly the 4.4 V threshold and 160 ms reset delay. Verify that the pinout remains compatible for potential board modifications. Ensure the replacement part meets the same environmental temperature specifications ranging from -40°C to +85°C.
