MAX921ESA Description

Short technical summary and product information.

The MAX921ESA is a single, micro-power, low-voltage comparator designed for single-supply applications. It features an internal 1.182V ±1% voltage reference and operates from a wide supply voltage range of +2.5V to +11V or ±1.25V to ±5.5V dual supply.

 

Key electrical characteristics include an ultra-low 4µA maximum quiescent current over the extended temperature range, a propagation delay of 12µs with a 10mV overdrive, and adjustable hysteresis. The comparator's TTL/CMOS-compatible outputs can sink and source current.

 

This device is ideal for battery-powered systems, threshold detectors, window comparators, and oscillator circuits. It is supplied in a compact 8-SOIC package, suitable for surface mount applications.

 

The MAX921ESA offers programmable hysteresis using the HYST pin and two resistors, simplifying circuit design without complex feedback equations. Its unique output stage minimizes parasitic feedback, making it easier to integrate into designs.
