This is probably a simple problem. I am trying to generate a DC with superimposed AC noise to do some noise tolerance test.
One way the OPA569 can be used as a summing amplifier and feed both AC noise and DC input to generate the output.
Instead of using it in summing amp configuration,
Is that possible to use function generator (i.e. 33250A or 33100A) with OPA569 as a buffer with the gain of 2 or 3 to generate the following output or any possible options?
