Rev 3; 3/95 _______________General Description The MAX921–MAX924 single, dual, and quad micro- power, 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 ...
