... Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... Output Loading and Stability Even with their low quiescent current of less than 150µA per op amp, the MAX492/MAX494/MAX495 are well suited for driving loads up to 1kΩ while maintaining DC accuracy. Stability while driving heavy capacitive loads is another key advantage over comparable CMOS rail- to-rail op amps ...

... Single-Supply Rail-to-Rail Op Amps The MAX492/MAX494/MAX495 can drive capacitive loads in excess of 1000pF under certain conditions (Figure 5). When driving capacitive loads, the greatest potential for instability occurs when the op amp is sourcing approximately 100µA. Even in this case, sta- bility is maintained with up to 400pF of output capaci- tance ...

... ADC, may be powered down most of the time. When power is reapplied to the MAX492/MAX494/ MAX495, it takes some time for the voltages on the sup- ply pin and the output pin of the op amp to settle. Supply settling time depends on the supply voltage, the ...
