  Hi, the datasheet clearly says that the input voltage must no go below the negative supply voltage. But this would be the case in your circuit, if the input offset voltage results in a voltage at the -input of OPAmp which is slightly negative compared…

  Michael Steffes

  So I went ahead and looked at the settling plot in the OPA2626, this is almost certainly a slew limited settling time, would be much faster if the input edge was slowed to stay out of slew limiting. Little history, This is a dual, non-power control, version…

  Hi Shane, have you thought about using the OPA837 or OPA625? These OPAmps have very low distortion specs at 100kHz. By the way, intermodulation can be identified by the appearance of sum and difference frequencies. Kai
