OpAmp - Inverting Comparator with Hysteresis

180

04:06:54

In this configuration the OpAmp works as a inverting comparator with hysteresis using a positive feedback.

It's very useful for signals with noise.

The hysteresis can be calculated by:
  Va = -Vsat.(R1/(R1+R2))
  Vb = +Vsat.(R1/(R1+R2))

Ps.: R2 is the resistor in the feedback loop
