Learn how to use op-amps to create passive averager and summer circuits that add or subtract multiple analog voltages. See the formulas, diagrams, and examples of these circuits and their applications.
22. Aug. 2013 · Learn how to use an operational amplifier (op-amp) to combine the voltages of two or more inputs into a single output. Find out the difference between inverting and non-inverting summing amplifiers, and see examples and equations.
26. Aug. 2013 · A summing circuit is a perfect example. A summing circuit is typically used in applications where many inputs or channels need to be added or subtracted together to form a composite output....
A summer circuit is one that sums, or adds, multiple analog voltage signals together. There are two basic varieties of op-amp summer circuits: noninverting and inverting.
