Inverting Summing Amplifier using Op Amp

Inverting Summing Amplifier using Op Amp

The inverting summing amplifier using op amp outputs a voltage equal to the sum of the voltages it has in its inputs. The following explanation is based on an adder of three inputs, but applies to an adder of any number of inputs

Window comparator using op amps

Window comparator using op amps

A window comparator using operational amplifiers lets you know if a signal (voltage level) is within or outside a previously defined acceptable voltage limit. Using a comparator or operational amplifier that controls the upper voltage level and another comparator that controls the lower voltage level, a window comparator can be implemented.
