APPLICATIONS
ADDING HYSTERESIS
To prevent oscillations at the output caused by noise or slowly
moving signals passing the switching threshold, positive
feedback can be used to add hysteresis to the noninverting parts
(ADCMP354 and ADCMP356).
Rev. 0 | Page 9 of 12
For the noninverting configuration shown in Figure 19, two
resistors are used to create different switching thresholds,
depending on whether the input signal is increasing or
decreasing in magnitude. When the input voltage is increasing,
the threshold is above V
REF
, and when it’s decreasing, the
threshold is below V
REF
.
The upper input threshold level is given by

VOLTAGE DETECTOR
The ADCMP35x parts can be used to monitor voltages, such as
battery monitoring or threshold detectors. Using a resistor
divider at the input to select the appropriate trip voltage, the
comparator can be configured to give a logic output when the
input passes that threshold. Figure 20 shows the typical
configuration of the ADCMP354 for monitoring a supply to
indicate that the voltage is above a certain level.
