MAX921EPA Description

Short technical summary and product information.

The MAX921EPA is a single micro-power, low-voltage comparator designed for single-supply applications. It features an internal 1.182V ±1% voltage reference, programmable hysteresis, and TTL/CMOS outputs. The device operates from a single +2.5V to +11V supply or a ±1.25V to ±5.5V dual supply.

 

Key electrical specifications include an ultra-low 4μA maximum quiescent current over the extended temperature range and a propagation delay of 12μs with a 10mV overdrive. The comparator also offers adjustable hysteresis and outputs that can sink and source current.

 

This comparator is ideal for battery-powered systems, threshold detectors, window comparators, and oscillator circuits. It comes in an 8-PDIP package and is designed for through-hole mounting.

 

The MAX921EPA's unique output stage minimizes parasitic feedback, making it easier to use in sensitive applications. Its input voltage range includes the negative supply rail, providing flexibility in design.
