Non-Inverting Comparator with Hysteresis
A non-inverting comparator with hysteresis requires a two
resistor network, and a voltage reference (V
) at the in-
verting input (
Figure 4
). When V
is low, the output is also
low. For the output to switch from low to high, V
IN
must rise
up to V
IN1
, where V
IN1
is calculated by
When V
is high, the output is also high. To make the
comparator switch back to its low state, V
must equal V
before V
A
will again equal V
REF
. V
IN
can be calculated by:
The hysteresis of this circuit is the difference between V
IN1
and V
IN2
.
