... Rev 1; 10/11 Low-Power Comparators with Precision General Description The MAX9644/MAX9645/MAX9646 are small, single com- parators, ideal for a wide variety of portable electronics applications such as cell phones, media players, and notebooks that have extremely tight board space and power constraints. These comparators are offered in both a miniature 4-bump UCSP™ ...

... Many microcon- troller digital inputs ports can be readily programmed to include these. The MAX9646 has a push-pull output stage that can both sink and source current, eliminating the need for an external pullup resistor. In this case, the MAX9646 uses the microcontroller’s power supply as V Applications Information Place a 0.1µ ...
