• AD8277 Absolute Value Circuit Distortion

    Hello, I'm trying to build Absolute Value Circuit as described in your application note here Your Absolute Value Circuit, with the AD8277. I was expecting to see a clean rectified wave but it turns out i get significant distortion even at 1kHZ and…

  • AD8277/AD8276 overvoltage/max input current

    Hi,

    We are using a AD8277 Unity-Gain Difference Amplifier and noticed that some parts spontaneous  break down which results in a short on their power pins.  I suspect this happens when a ungrounded device is connected to the inputs. This device floats…

    Adam,

      I can't find AD8577??  Did you mean AD8277??  AD8677??

  • RE: Advice on Implementing a Precision Full Wave Rectifier

    Hi David,

    Sorry if we missed this thread. Please see below for my answers.

    1. The AD8277 is a difference amplifier with four on-chip resistors that are laser trimmed for excellent gain accuracy and CMRR. The "R": in figure 3 is the on-chip resistor…

  • gain reduction of opamp at high frequency

    Hi,

    We are using opamp IC AD8277 along with AD8479 for one of our applications.Upto certain frequencies(7khz)the output amplitude is obtaining somewhat correct as per the gain.But as the frequency is increased,the gain is getting reduced.Can you please…

  • RE: AD8276 output capacitive load drive capability

    The AD8276 (and AD8277/78/79) can drive ~200pF without adversely affecting settling time and overshoot.  You can drive a higher capacitive load, but it may increase the settling time and overshoot.  Or you can add a small resistor (~20 ohms) in series with…

  • RE: Is it possible to precision rectify a 1MHz signal?

    It is always nice to be able to answer one's own questions, since it usually means, that the effort to find out has been succesful.
    I tried to build the circuit mentioned in this publication:
