PRODUCTION DATA.
Most comparators have rather low gain. This allows the output to spend time between high and low when the input signal changes slowly. The result is the output may oscillate between high and low when the differential input is near zero. The high gain of this comparator eliminates this problem. Less than 1 μV of change on the input will drive the output from one rail to the other rail. If the input signal is noisy, the output cannot ignore the noise unless some hysteresis is provided by positive feedback. (See Hysteresis.)
