MAX9021AXK-T Description

Short technical summary and product information.

The MAX9021AXK-T is a general-purpose comparator from Analog Devices / Maxim Integrated, optimized for low-power consumption and fast output response. It is designed for single-supply applications operating from 2.5V to 5.5V, with a typical supply current of 2.8µA per comparator.

 

Key electrical characteristics include a 3µs propagation delay and 4mV of internal hysteresis for noise immunity. The output swings rail-to-rail, and the input common-mode range extends to the negative supply. The device is available in a compact SC-70-5 package, making it suitable for space-constrained portable systems.

 

Applications for this comparator include battery-powered systems, mobile communications, sensor-signal detection, and threshold detectors. Its combination of low power, single-supply operation, and small footprint makes it an ideal choice for various portable electronic designs.
