  • RE: OPA211: Inverting application of OPA211 failure

    Resolved
    Hi Eric, You missed the input Vcm requirements for OPA211. The V+ node is 0.227V and V4 generator needs DC biased at 2.5V. Please try the following. I configured 2.5V at V+ with 200||2kohm, and DC biased the generator at 2.5V with 100mV riding on…

  • RE: OPA211: OPA211 powered single-supply 3.3V?

    Resolved
    Hi Andreas, The datasheet recommended to have minimum voltage of 4.5V as operating conditions in a single voltage supply. Even if the part works at 3.3V, it may not get the linear responses the op amp output. Using 4.5V as the single rail power supply…
