... The output stage employs a unique design that mini- mizes supply-current surges while switching, which vir- tually eliminates the supply glitches typical of many other comparators. The MAX9015/MAX9017/MAX9019 have a push-pull output stage that sinks as well as sources current. The MAX9016/MAX9018/MAX9020 have an open-drain output stage that can be pulled beyond ...

... Additional hysteresis can be generated using positive feedback, but the formulas differ slightly from those of the MAX9015/MAX9017/MAX9019. Use the following procedure to calculate resistor values: 1) Select R3. Input bias current at IN_+ is less than 2nA, so the current through R3 should be at least 0.2µ ...
