• RE: AD8229 vs AD8228

    Hi Harry,

    I work for NASA in the instrument electronics area.  The AD8229 works very well in my design, however I don't really need the higher temperature capability of the part.  So, I may look for an alternative to keep the cost of a prototype down…

  • AD8229/8429 and Multisim Model

    I have been using the Analog Devices version of Multisim for a while and just downloaded version 12. I modeled a simple amplifier using the AD8429.

    Signal on the negative input, positive input grounded, +/-15V, gain resistor of 60.4 ohms for a gain of…

  • RE: AD8429 Output Noise

    A little more information for other people facing a similar problem.  I was able to get my output noise measurement down to 162 nV/rtHz ( I had some extra resistance at the input that wasnt exactly matching the circuit above).

    I also noticed the datasheet…

  • RE: Help selecting a high gain amp


    I would use an Instrumentation Amp with a stable 1V on one side.  Look at AD8421, AD8428, AD8229, or AD8226.


  • RE: Is it possible to set AD9959 eval board generate lower frequencies

    Two other in-amps that come close to enough bandwidth are the AD8229 and AD8429.  Gain of these parts is set by an external resistor.

  • RE: Instrumentation amplifer noise calculations

    Hi Jeremy,

    The noise of the gain resistor is not taken into account in the noise spec, although these resistors are usually small and do not greatly affect the noise. Include it in your voltage noise equation: Voltage RTI noise = √(eni2 + (eno/G)2

  • RE: PCB layout for AD8429 or AD 8421

    Hi Emman,

    I am very grateful of your swift reply. Definitely, we will use AD8229 for the other applications as the operating temperature is very high.

    Many thanks to your reply again.

    Thank you.
