I required a 20Vpp (+/-10Vp) from the ADA4898 Amplifier.
Here with i attached a Simulation Circuit of ADA4898 in inverting summing amplifier.
Here the input is sine wave with -10Vpp and it is added with DC offset +10V.
The gain for sine wave input is two and the DC offset input have gain as one.
I had doubt whether the signal added first then gained by operational amplifier ? or Gained by opamp first then it is added on the output.?
