... CC Applications Information Power-Supply Considerations The MAX4289 operates from a single 1.0V to 5.5V supply and consumes only 9µA of supply current. A high power- supply rejection ratio of 75dB allows the amplifier to be powered directly off a decaying battery voltage, simplify- ing design and extending battery life. The MAX4289 is ideally suited for single-cell battery-powered systems ...

... Using the MAX4289 as a Comparator Although optimized for use as an operational amplifier, the MAX4289 can also be used as a rail-to-rail I/O com- parator (Figure 5). External hysteresis can be used to minimize the risk of output oscillation. The positive feed- back circuit, shown in Figure 5, causes the input thresh- old to change when the output voltage changes state ...
