Ultra Low-Power, Single/Dual-Supply Comparators _______________Detailed Description The MAX921–MAX924 comprise various combinations of a micropower 1.182V reference and a micropower comparator. The Typical Operating Circuit shows the MAX921 configuration, and Figures 1a-1c show the MAX922–MAX924 configurations. Each comparator continuously sources up ...
