  • RE: OPA350: Measured output is double simulated (expected) output level - Pt2

    Yes. i meant a bad connection between CM_BIAS and pin 3. A bad connection may be caused by any number of things: - cold solder joint - frayed or exposed wires causing unintended shorts - loose connections - corroded connections or insulation - faulty switches…

  • OPA350: true-GND output technique

    Resolved
    Part Number: OPA350 Other Parts Discussed in Thread: OPA863A , Tool/software: Hi to everyone, I'd like to apply the technique described on TIDU018 about true-GND output on single-supplied opamps, but it seems linked to CMOS AB-class output stages…

  • RE: OPA350: Measured output is double simulated (expected) output level

    Mark, Marek is on travel for the next few weeks. I can help you while he is out. If the result of your test shows the resistors to be both 1k as expected, I would suggest replacing the OPA350 with a new OPA350 (perhaps it was damaged during the debug)…
