Introduction

The MAX923CPA is a dual, general-purpose voltage comparator that operates from a single 2.5V to 11V supply or dual ±1.25V to ±5.5V supplies. It features a typical input offset voltage of 10mV, a typical propagation delay of 12μs, and a typical quiescent current of 7.5μA. This comparator is well-suited for a variety of applications, including threshold detection, zero-crossing detection, and simple analog-to-digital conversion.
