• AD8676 :input voltage exceeds the common mode voltage range


    I have a question.

    Does AD8676 will occur "phase reversal" when the input voltage exceeds the common mode voltage range within supply voltage range?

    Ex. AD8672  D/S Page 1  "No phase reversal"

    In this regard, the same as the

    Hi everyone,

    My Situation:

    If build a circuit with some filter capacitors (10uF) an the input's of the OpAmp AD8676 and have the problem that after some time (days of power up/down) suddenly the OpAmp start to leak at it's positive input an sink about…

  • RE: Spice Opamp model noise

    Hi John,

    Thank you for your question. I have tried AD8676 noise simulation in Multisim and produced the same results as yours. I believe that the AD8676 noise model has an issue and that I will forward this to the group that modeled the AD8676 SPICE…

  • RE: SPICE model for OpAmp Noise

    Hi Kapati,

    Apologies for the delayed response. The AD8676 spice model  is currently being modified. For the meantime,  you may use the AD8675 model instead. AD8676 is a dual of AD8675.



  • AD5791 Reference Buffer Opamps

    The data sheet and reference designs recommend the AD8676 for voltage reference buffers.  I would like to use an opamp that draws less supply current than the 3.4mA max of the AD8676.  The ADA4077-2 looks to have similar performance specs, and draws only…

        That was a very helpful piece of information.Thanks.

    1. If I select voltage signals for both channel1 and channel2 ,the voltage will pass through the ADG1414 and then to AD8676.But in this case ,won't the voltages overlap?
    2. I want to modify…

    I'm tempted to use AD8675/AD8676 but I have a couple of open questions:

    In the parametric search, the input voltage headroom for AD8675/AD8676 is given as 1.5V (typ) and 2.5V (max).

    Under what conditions do I have to consider the max specification…
