MAX917EUK

Comparators Overview

The MAX917EUK+T is a nanopower analog comparator from Analog Devices/Maxim Integrated, housed in an SOT-23 package. It operates on a single supply voltage ranging from 1.8V to 5.5V and consumes only 750nA of quiescent current. The device features a beyond-the-rails input capability, allowing it to handle signals exceeding the supply rails. It provides an open-drain output capable of sourcing up to 50mA. Key electrical specifications include a maximum input offset voltage of 5mV and an input bias current of 1nA. It functions as a general-purpose comparator with an internal reference.

Comparators Feature Summary

• Nanopower operation with ultra-low supply current consumption
• Beyond-the-rails input capability for handling out-of-range signals
• Open-drain output stage supporting high drive currents
• General-purpose design with integrated reference

Comparators Applications

• Battery-powered sensor interfaces
• Low-voltage signal monitoring
• Threshold detection circuits
• Portable instrumentation

Comparators Procurement Notes

Verify the exact suffix (e.g., +T) for reel packaging requirements. Confirm RoHS compliance status through official documentation. Check for obsolescence notices or lifecycle changes. Ensure the supplier provides valid traceability data. Validate pinout compatibility with existing PCB footprints before integration.

Comparators Selection Notes

Select this component when ultra-low power consumption is critical alongside rail-to-rail input flexibility. The open-drain output requires appropriate pull-up resistor selection based on load requirements. Consider the 5mV offset voltage for precision applications. Verify that the 120us response time meets system timing constraints.

Comparators Part Context

This part belongs to the Maxim Integrated nanopower comparator family, designed for battery-operated systems. It complements other low-power devices by offering robust input protection and simple interface capabilities. The SOT-23-5 package allows for compact board layouts in space-constrained portable electronics.

Comparators Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify if newer revisions offer improved offset voltage or lower current draw. Ensure any substitute maintains the beyond-the-rails input specification.
