... TTL/CMOS outputs that sink and source current. Ideal for single-supply applications, the MAX931-MAX934 operate from a single +2.5V to +11V supply (or a ±1.25V to ±5V dual supply), and each comparator’s input voltage range extends from the negative supply rail to within 1.3V of the positive supply. The MAX931-MAX934’ ...

... Ultra Low-Power, Low-Cost Comparators with 2% Reference _______________Detailed Description The MAX931-MAX934 comprise various combinations of a micropower 1.182V reference and a micropower comparator. The Typical Operating Circuit shows the MAX931 configuration, and Figures 1a-1c show the MAX932/MAX933/MAX934 configurations. Each comparator continuously sources up to 40mA, and the unique output stage eliminates crowbar glitches during output transitions ...

... The MAX932 and MAX933 do not have a GND pin, and their outputs swing from V+ to V-. Connect V- to ground and +5V supply to achieve TTL compatibility. The MAX931-MAX934’s unique design achieves an output source current of more than 40mA and a sink current of over 5mA, while keeping quiescent currents in the microampere range ...

... Hysteresis can be set with two resistors using positive feedback, as shown in Figure 4. This circuit generally draws more current than the circuits using the HYST pin on the MAX931/MAX932/MAX933, and the high feedback impedance slows hysteresis. The design procedure is as follows: 1. Choose R3. The leakage current of IN+ is under 1nA (up to +85° ...

... BATT This circuit takes advantage of the four key features of the MAX931: 2.5µA supply current, an internal reference, hysteresis, and high current output. Using the component values shown, the three-resistor voltage divider programs the maximum ±50mV of hysteresis and sets the IN- voltage at 100mV ...
