How does summing amplifier work?
The label must be mysterious it actually compare two or more signal input and amplify the result. example if bot inpust have the same scaling resistor but the signal is -5v and +5 volt the output will be zero. Read More »

wikipedia, go! Although it doesn't answer the second part of your question. In the wiki example for the summing amplifier, you set R1 to a value, let's say 1kohm. Put R2 as 2*R1, and R3 as 2*R2, and R4 as 2*R3 and so on. You need one resist...

The summing amplifiers that I know, are those used to do analogue computations: the input is two or more voltages and the output is a voltage that is the addition of the input voltages. The limitation is their power supply voltage as it lim...

all of them. Any design has to consider all of the parameters of all the components. The parameters are listed for that very reason. Now usually, a lot of them can be neglected as not relevant, but you have to know that. In your case, the o...
