ADM693ANZ

Supervisors Overview

The ADM693ANZ is a microprocessor supervisory circuit manufactured by Analog Devices, designed for reliable power system monitoring in digital applications. It operates within a maximum supply voltage of 5.5 V and monitors a single input with thresholds ranging from 4.25 V to 4.48 V. The device features programmable clock outputs and power-fail detection capabilities. Encased in a 16-pin PDIP package for through-hole installation, it supports active-high and active-low output drivers. The reset activity time is specified at 70 ms, ensuring stable system initialization. Operating temperatures range from -40°C to +85°C, providing robust performance across industrial environments.

Supervisors Feature Summary

• Integrated power-fail detection for continuous voltage supervision
• Programmable clock output functionality for timing control
• Configurable active-high or active-low output drivers

Supervisors Applications

• Microprocessor reset circuits
• Power supply monitoring systems
• Industrial control units

Supervisors Procurement Notes

Verify the specific suffix 'ANZ' corresponds to the PDIP-16 through-hole package variant when sourcing. Confirm that the required reset delay aligns with the 70 ms specification documented for this package type. Ensure compatibility with the 4.25 V to 4.48 V monitoring range for your target application voltage. Cross-reference the manufacturer's latest datasheet to confirm current production status and lead times, as availability may vary by region.

Supervisors Selection Notes

Select the ADM693ANZ when a through-hole mounting solution is required for microprocessor supervision. This model is appropriate for designs needing programmable clock outputs alongside standard reset functions. Consider the 70 ms reset delay and the specific over-voltage threshold of 4.48 V against your system requirements. Compare against surface-mount variants like the ARZ if PCB space constraints differ. Verify that the 5.5 V maximum supply rating matches your power rail specifications.

Supervisors Part Context

The ADM693A series represents a family of CMOS supervisory circuits designed for monitoring single power supplies. The ADM693ANZ specifically denotes the plastic dual in-line package version, distinguishing it from surface-mount options like the SOIC-16 (ARZ). These devices are part of Analog Devices' broader portfolio of power management integrated circuits, focusing on reliability and precise threshold detection for digital logic protection.

Supervisors Replacement Considerations

The ADM693ARZ serves as a direct functional equivalent in a surface-mount SOIC-16 package. The MAX693ACWE+T offers similar supervisory features but utilizes a wide SOIC package and may exhibit different electrical characteristics such as a 200 ms reset delay. Verify pinout compatibility and threshold voltages before substituting.
