ADM696AR

Supervisors Overview

The ADM696ARZ is a CMOS supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage rails. It operates within a supply voltage range of 3 V to 5.5 V and features a fixed threshold voltage of 1.3 V. The device provides both active high and active low push-pull reset outputs with a minimum reset delay time of 35 ms. It includes battery backup functionality and is housed in a 16-SOIC surface-mount package, operating across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides dual active high and active low push-pull reset signals for flexible logic interfacing
• Integrates battery backup switch capability to maintain system state during power transitions
• Features a fixed 1.3 V threshold for precise low-voltage monitoring applications

Supervisors Applications

• CMOS microprocessor and memory system supervision
• Battery-powered equipment requiring backup switching
• Portable electronic devices with strict voltage monitoring needs

Supervisors Procurement Notes

Verify the specific suffix (e.g., ARZ vs AR) as it determines RoHS compliance and packaging type. Confirm availability status, as some variants may be limited or end-of-life. Ensure the 16-SOIC package matches your PCB footprint requirements. Cross-reference datasheet revision dates to confirm electrical characteristics remain consistent with current design specifications.

Supervisors Selection Notes

Select this component when a fixed 1.3 V threshold is required for CMOS logic families. The dual output configuration simplifies interface design compared to single-output supervisors. Consider the 35 ms reset delay for timing-sensitive applications. Verify that the 1.3 V threshold aligns with the lowest acceptable operating voltage of the monitored circuit to prevent premature resets.

Supervisors Part Context

The ADM696 belongs to the ADM69x series of voltage supervisory circuits from Analog Devices. This family focuses on providing reliable reset generation for digital systems. The ADM696 specifically targets applications requiring a low threshold voltage and battery backup support. It serves as a critical component for ensuring system stability during power-up and power-down sequences in embedded designs.

Supervisors Replacement Considerations

The ADM8696ARWZ is documented as a parameter-equivalent replacement. The MAX696EWE+ is listed as a direct substitute. Verify pinout compatibility and electrical parameters before substitution.
