• AD8638: Temperature variation

    The spice model on the web page
    http://www.analog.com/en/products/amplifiers/operational-amplifiers/zero-drift-a
    mplifiers/ad8638.html#product-overview   appears to be much more sensitive to
    temperature than I would expect.  It is more sensitive…
  • AD8638: Inpput range at +-5V supply

    I use ad8638 with +-5V dual supply.
    Could You tell me please what is the input voltage range? I can't find this
    value in the datasheet!

     

    With dual supply operation +-5V there is a valid input voltage range for AD8638
    of
    -4…
  • RE: AD8638 - is it possible to bootstrap the power rails to decrease Cin common mode?

    Hi John,

    Apologies for the late response. Yes, I already sent you an email using the one registered in your engineer zone account.

  • AD8638 Gain issue

    Dears,

            There's application that use AD8638 in RF receive front end. And  use it under third order intermodulation situation(input signal frequency is 60MHz) there just up to 28dBm(and the data sheet note it can meet 33dBm)  . Does there any advice…

  • AD8638 Input Bias vs. Offset-Current

    In the datasheet for the AD8638 I don´t understand how the input offset current can be much larger than the inbut bias current.

    E.g. on page 4 of the datasheet at the specs for V(sy)=16V there is 1pA/75pA (typ./max.) input bias current at 25°C,…

  • AD8638 weird behaviour

    Hello

    I'm testing a simple circuit with the AD8638 Op Amp.

    The Amplifier is supplied with 12 VDC single supply and works as a kind of voltage limiter. The limiting voltage should be 9.9 V which is derived from a voltage reference.

    The auto zero…
