... A +1.6V to +5.5V single-supply operating voltage range makes the MAX965 family of comparators ideal for 2-cell battery-powered applications. The MAX965/MAX967/ MAX968/MAX969 offer programmable hysteresis and an internal 1.235V ±1.5% reference. All devices are available in either space-saving 8-pin µ ...

... Typical comparators consume orders of magnitude more current during switching than during steady-state operation. With the MAX965 family of comparators, during an output transi- tion from high to low, the output slew rate is limited to minimize switching current. Voltage Reference With V greater than 1 ...

... Hysteresis can be generated with three resistors using positive feedback (Figure 4). This method generally draws more current than the method using the HYST pin on the MAX965/MAX967/MAX968/ MAX969. Also, the positive feedback method slows hysteresis response time. Use the following procedure to calculate the resistor values: 1) Select R3 ...
