MAX923ESA+

The MAX923ESA+ is a dual micropower low voltage comparator in 8 pin NSOIC package. This ultra low power comparator includes an internal 1.206 ±1% voltage reference, programmable hysteresis and TTL/CMOS outputs that sink and source current. It is ideal for 3V or 5V single supply applications and each comparator's input voltage range swings from negative supply rail to within 1.3V of positive supply. The unique output stage of MAX923 continuously sources 40mA current and by eliminating power supply glitches that commonly occur when comparators change logic states, MAX923 minimize parasitic feedback which makes it easier to use. The dual MAX923 provides unique and simple method for adding hysteresis without feedback and complicated equations simply by using the HYST pin and two resistors. It is used in battery powered systems, threshold detectors, window comparators and oscillator circuits.
