... Rev 3; 2/07 Ultra-Low-Voltage, Rail-to-Rail I/O Comparators General Description The MAX965–MAX970 single/dual/quad micropower comparators feature rail-to-rail inputs and outputs, and fully specified single-supply operation down to +1.6V. These devices draw less than 5µA per comparator and have open-drain outputs that can be pulled beyond (max) above ground ...

... MAX968 is similar to the MAX967, but is configured as a window comparator. The MAX969 is a quad com- parator with a common hysteresis adjustment and a ref- erence output pin. The MAX970 is a quad comparator without a reference and without hysteresis adjustment. (See Functional Diagrams and Selector Guide.) The MAX965– ...

... This tends to occur when the voltage on one input is equal or very close to the voltage on the other input. The MAX965–MAX970 have internal hysteresis to counter parasitic effects and noise. In addition, with the use of external resistor, the MAX965/MAX967/ MAX968/MAX969’ ...

... This is apparent only when programming addi- tional hysteresis using the HYST pin. The hysteresis band is constant when HYST is connected to REF. The MAX966/MAX970 do not have a HYST pin for pro- gramming hysteresis. Hysteresis can be generated with three resistors using positive feedback (Figure 4). This ...
