Importing AD8237 spice model to LTspice XVII

Hi all,

I've read several topics on how to import a new spice model to LTspice, but I need to import the spice module of the AD8237 (which can be found on AD site in .cir format), but nothing seems to work. I am still not able to see the component under the library list. 

Could someone please guide me on how to do this?

Any kind of help would be highly appreciated.

  • Hi Helmuts,

    Thanks a lot. Seems to be working fine. Just a quick question, does this model include the noise generated by the IA etc? or it only simulates its ideal operation?

    Hello,

    Often there are comments in the model file. When you open the model file AD8327.cir, you will see the information below.


    * Not Modeled:
    *   Temperature effects
    *   CM SR limitation
    *
    * Parameters modeled include:
    *   Gain
    *    Bandwidth
    *    Noise
    *    CMRR vs. frequency
    *    PSRR vs. frequency
    *    Vosi
    *    Ibias/Ios
    *    Ibias vs. VCM
    *    Ibias vs. Vdiff
    *    Input Capacitance
    *    Quiescent Current
    *    Input/Output clamping
    *    Max Diff Input limitation
    *    Gain Error
    *    Pulse vs. cap load

    Yes, noise is modelled in the noise analysis. The noise analysis have to be done with the simulation command .NOISE . Please be aware that no other type of simulation, e.g. .TRAN or .AC, will contain noise.
