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 de ago. de 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.
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.
An adder, or summer, is a digital circuit that performs addition of numbers. In many computers and other kinds of processors, adders are used in the arithmetic logic units (ALUs).
The traditional inverting op-amp summer configuration exploits the feature of a low impedance node (virtual ground) at the inverting input. The summing circuit is straightforward...
