... The MAX971–MAX974/MAX981–MAX984 comprise various combinations of a micropower 1.182V reference and micropower comparators. The Typical Operating Circuit shows the MAX971/MAX981 configuration, and Figures 1a–1d show the MAX9_2–MAX9_4 configurations. Internal hysteresis in the MAX9_1, MAX982, and MAX9_3 provides the easiest method for implementing hysteresis ...

... The internal bandgap voltage reference has an output of 1.182V above V-. Note that the REF voltage is referenced to V-, not to GND. Its accuracy is ±1% (MAX971/MAX973/MAX974) or ±2% (MAX981–MAX984) in the 0°C to +70°C range. The REF output is typically capable of sourcing 25µA and sinking 15µA. Do not bypass the REF output ...

... HB twice the voltage between REF and HYST. The HYST input can be adjusted to a maximum voltage of REF and to a minimum voltage of (REF - 50mV). The maximum difference between REF and HYST (50mV) will therefore produce a 100mV (max) hysteresis band. ...
