MAX9117EXK-T

Overview

The MAX9117EXK-T is a nanopower analog comparator in a space-saving SC70-5 package. It features an internal 1.252V reference and draws 600nA supply current. The device operates down to +1.6V with Beyond-the-Rails inputs extending 200mV beyond the rails. It has a push-pull output stage capable of ±5mA drive, ensuring rail-to-rail swing. Propagation delay is typically 14µs at 5V. Operating temperature range is -40°C to +85°C.

Procurement Notes

Verify the exact part number against official manufacturer documentation to ensure compatibility with specific design requirements. Confirm that the ordering suffix matches the desired package and RoHS status. Cross-reference electrical specifications with the latest datasheet revision to account for any updates or changes in performance characteristics over time.

Selection Notes

Select this component when ultra-low power consumption is critical alongside compact packaging. The integrated reference simplifies circuit design by eliminating external components. Ensure the application voltage stays within the specified operating range. Consider the push-pull output capability for direct driving of logic interfaces without additional pull-up resistors.

Part Context

This device belongs to the MAX9117–MAX9120 family of nanopower comparators. These devices are designed for low-voltage, low-power applications. The family includes variants with and without internal references and different output stages. They share common features like Beyond-the-Rails inputs and crowbar-current-free switching.

Replacement Considerations

Check for pin-compatible alternatives within the same family, such as the MAX9119EXK-T if the internal reference is not needed. Verify that substitute parts meet the required supply current and propagation delay specifications. Ensure the replacement supports the necessary output drive current and voltage levels.
