NCS2220AMUT1G

The NCS2220A is an industry first sub−one volt, low power comparator. This device is designed for rail−to−rail input and output performance. This device consumes only 7.5 μA/Comparator of supply current while achieving a typical propagation delay of 0.5 μs at a 20 mV input overdrive. This comparator is guaranteed to operate at a low voltage of 0.85 V up to 6.0 V. This is accomplished by the use of a modified analog CMOS process that implements depletion MOSFET devices. The common−mode input voltage range extends 0.1 V beyond the upper and lower rail without phase inversion or other adverse effects. This device has a typical internal hysteresis of ± 8.0 mV. This allows for greater noise immunity and clean output switching.
