Customized SPICE Model for AD8421BRZ

HI Sijo,

I got SPICE Model for AD8421(AD8421.cir) from AD website.

But this AD8421.cir model has different VOSI & VOSO values, it is not matching with AD8421BRZ(VOSI=25uV & VOSO=250uV) parameters as per datasheet. 

Could you please provide customized SPICE model for AD8421BRZ, it should include all the parameters(VOSI, VOSO,  etc..) as per the AD8421BRZ datasheet values.

It is urgent requirement, please provide ASAP.

    Hi Tatarao K,

    Correct, this model has 250uV output offset voltage.

    With regards to the layout, we always recommend that traces on Rg pins should be as short as possible and preferably on the top layer to minimize parasitic inductance.

    Please check the layout guide on page 18 of this datasheet.

    I hope this helps. 

    Best regards,
