APPLICATIO S I FOR ATIO
LT1713/LT1714
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.
