Detailed Description 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 ...

Information 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 ...
