... 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. It also produces faster hysteresis action and consumes much less current than circuits using external positive feedback ...

... Hysteresis increases the comparators’ noise margin by increasing the upper threshold and decreasing the lower threshold (Figure 2). Hysteresis (MAX9_1/MAX982/MAX9_3) To add hysteresis to the MAX9_1, MAX982, or MAX9_3, connect resistor R1 between REF and HYST, and connect resistor R2 between HYST and V- (Figure 3 hysteresis is required, connect HYST to REF. When hysteresis is added, the upper threshold increases by the same amount that the lower threshold decreases ...
