Learn how to use a passive averager and an op-amp summer circuit to sum multiple analog voltages. The web page explains the concept of Millman's Theorem, the difference between non-inverting and inverting summer circuits, and the advantages of using op-amps for these applications.
22 de ago. de 2013 · Learn how to use an operational amplifier circuit to combine the voltages of two or more inputs into a single output. The summing amplifier can be inverting or non-inverting, and can be modified by changing the input impedances, gains, and feedback resistors. See examples, formulas, and applications of summing amplifiers.
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.
