Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required operating temperature range and package type for your design. Cross-reference the manufacturer's datasheet for any recent product change notifications that may affect performance or availability.

Supervisors Selection Notes

Select this component when a fixed 3.3V supervision threshold is required for standard logic families. Consider the low quiescent current for battery-operated designs. Verify that the open-drain output capability aligns with the pull-up requirements of the target microprocessor reset input. Evaluate the 140ms timeout against the startup time of the controlled system.

Supervisors Part Context

This part belongs to the LTC690 family of microprocessor supervisory circuits from Analog Devices. The family includes variants with different thresholds and packages, such as the LTC690, LTC691, and LTC694. These components are designed to provide essential power management functions in embedded systems, ensuring reliable operation under varying power conditions.

Supervisors Replacement Considerations

Direct replacements include other members of the LTC690 family, such as the LTC690 series, provided they match the 3.3V threshold and PDIP-16 package. Verify functional equivalence regarding reset timeout and output configuration before substitution.
