... The output stage’s unique design limits supply-current surges while switching, virtually eliminating the supply glitches typical of many other comparators. The MAX987/MAX991/MAX995 have a push-pull output stage that sinks as well as sources current. Large inter- nal output drivers allow rail-to-rail output swing with loads up to 8mA ...

... Unfortunately, this method also slows hysteresis response time. Use the following procedure to calcu- late resistor values for the MAX987/MAX991/MAX995. 1) Select R3. Leakage current under 10nA; therefore, the current through R3 should be at least 1µA to minimize errors caused by leakage current. ...

... THR THF MAX988/MAX992/MAX996 The MAX988/MAX992/MAX996 have ±2.5mV internal hysteresis. They have open-drain outputs and require an external pullup resistor (Figure 2). Additional hys- teresis can be generated using positive feedback, but the formulas differ slightly from those of the MAX987/MAX991/MAX995 ...
