Supervisors Procurement Notes

Verify the specific suffix AR-REEL indicates reel packaging for the ADM695 series. Confirm compatibility with existing board layouts requiring SOIC-16 surface mount packages. Check for any lead-free or RoHS compliance requirements if applicable to your manufacturing standards. Ensure the open-collector output configuration matches your system's pull-up resistor design.

Supervisors Selection Notes

Select this component when a comprehensive supervisory solution is required for 5V CMOS systems. It is suitable for designs needing integrated watchdog, reset, and battery backup management in a compact package. Consider the open-collector output type and 200 ms reset delay for timing-sensitive applications. Verify that the 4.65 V threshold aligns with your system's voltage monitoring requirements.

Supervisors Part Context

The ADM695 belongs to the ADM690–ADM695 family of supervisory circuits designed for microprocessor systems. This family offers various configurations to satisfy most system requirements, including reset assertion, backup switching, and memory protection. The ADM695 specifically targets 5V CMOS applications with integrated power management features.

Supervisors Replacement Considerations

The ADM695ANZ is a PDIP-16 through-hole equivalent with similar electrical characteristics. For surface-mount alternatives, verify other ADM69x variants with matching thresholds and output types. Cross-reference with MAX695 equivalents if pin-compatible replacements are needed.
