The MAX921–MAX924 single, dual, and quad micropower, low-voltage comparators feature the lowest power consumption available. These comparators draw less than 4µA supply current over temperature (MAX921/MAX922), and include an internal 1.182V ±1% voltage reference, programmable hysteresis, and TTL/CMOS outputs that sink and source current.Ideal for 3V or 5V single-supply applications, the MAX921–MAX924 operate from a single +2.5V to +11V supply (or a ±1.25V to ±5V dual supply), and each comparator's input voltage range swings from the negative supply rail to within 1.3V of the positive supply.The MAX921–MAX924's unique output stage continuously sources as much as 40mA. And by eliminating power-supply glitches that commonly occur when comparators change logic states, the MAX921–MAX924 minimize parasitic feedback, which makes them easier to use.The single MAX921 and dual MAX923 provide a unique and simple method for adding hysteresis without feedback and complicated equations, simply by using the HYST pin and two resistors.ApplicationsBattery-Powered ApplicationsOscillator CircuitsThreshold DetectorsWindow Comparators
