... Detailed Description The MAX9015–MAX9018 feature an on-board 1.24V ±0.5% (±1.45% for the B grade) reference, yet draw an ultra-low supply current. The MAX9019/MAX9020 (duals without reference) consume just 850nA of supply current. All devices are guaranteed to operate down to 1.8V supply. Their common-mode input voltage range extends 200mV beyond-the-rails ...

... 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 ...
