  • OPA2237: using OPA2237 as a comparator (without feedback resistor) whose non-inverting input becomes abruptly negative

    Resolved
    Part Number: OPA2237 Other Parts Discussed in Thread: LM393 Hello, We are planning to use OPA2237 as a comparator where the input signal is not slow moving, but changes abruptly at the non-inverting input to a negative value. I am posting this question…

  • RE: OPA2237: opamp with with input common mode voltage extending below ground

    Resolved
    Hi Nitish, this does only mean that you can give 0V to the one input and 14V to the other input without damaging the chip. But applying -2V directly to the input will damage the chip. Kai

  • RE: LM393: how much negative input voltage at non-inverting input (and how much current) can cause damage?

    Resolved
    Hi Paul, Thank you for your response. We can definitely increase the values of the divider resistors. Would you mind clarifying what you mean by "...which will then clamp earlier."? FYI, this particular LM393 comparator circuit doesn't encounter…
