Procurement Notes
Verify the specific suffix TCKN against official Analog Devices documentation to confirm exact packaging and tape-and-reel specifications. Ensure the component matches the standard MAX9025EBT+ electrical characteristics. Confirm RoHS compliance status through the manufacturer's declaration. Validate that the part number corresponds to the correct temperature grade and package variant before procurement.
Selection Notes
Select this component for applications requiring minimal footprint and ultra-low power consumption. The integrated 1.236V reference simplifies circuit design by eliminating external components. The Beyond-the-Rails input range allows sensing near the supply rails. Ensure the system voltage meets the minimum operating requirement of 1.8V for proper functionality.
Part Context
This part belongs to the MAX9025/MAX9028 nanopower comparator family designed for battery-powered devices. These comparators are optimized for mobile communications, notebooks, and medical instruments where power efficiency and size are critical constraints. The family offers both versions with and without internal references.
FAQ
What is the supply current of the MAX9025?
The MAX9025 draws an ultralow supply current of only 1µA due to its internal reference.
Does the MAX9025 support inputs beyond the supply rails?
Yes, it features Beyond-the-Rails inputs that extend 200mV beyond the supply lines.
