Op-amp Summing Amplifier

Started by Patrick Chung March 16, 2015
Good feature of op-amp summing amplifier is that there is direct current pa=
th provided from every input to the output. For that reasons input voltage =
sources don't need to have current sink capability.
Good feature of op-amp non inverting summing amplifier is that output volta=
ge is proportional with the sum of the input signals, and with the same sig=
n. Bad feature is that there is no direct current path from the inputs to t=
he output, so input voltage sources must have sinking current capability.=
