Hysteresis

Another useful technique to avoid oscillations is to provide

positive feedback, also known as hysteresis, from the

output to the input. Increased levels of hysteresis, how-

ever, reduce the sensitivity of the device to input voltage

levels, so the amount of positive feedback should be

tailored to particular system requirements. The

LT1713/LT1714 are completely flexible regarding the ap-

plication of hysteresis, due to rail-to-rail inputs and the

complementary outputs. Specifically, feedback resistors

can be connected from one or both outputs to their

corresponding inputs without regard to common mode

considerations. Figure 2 shows several configurations.
