... General Description The MAX9647/MAX9648 comparators are drop-in, pin-for- pin compatible replacements for the LMX331/LMX331H. The MAX9648 has the added benefit of internal hyster- esis to provide noise immunity, preventing output oscilla- tions even with slow moving input signals. Advantages of the ICs include low supply voltage, small package, and low cost ...

... They require approximately 60FA per comparator with a 5V supply and 52FA with a 2.7V supply. The MAX9648 has 2mV of hysteresis for noise immunity. This significantly reduces the chance of output oscilla- tions even with slow moving input signals. The ICs are ideal for automotive applications because they oper- ate from -40NC to +125NC ...
