• RE: AD8475 CMRR

    Hi Phil.

    My mistake: I forgot about differential gain. So you are right: we get Acm= 20uV/V when AD8475 configured to 0.4 gain. But what about value of input CM voltage reffered to AD8475 in my example above: I think it is 2.5V not 5V cause AD8475 in…

  • Modeling AD8475

    Hi, engineers.

    I have one problem. When I simulated schematics with AD8475, on out i get voltage 2.5kV. I think spice-model AD8475 aren't correct. Are you can check this spice-model?

  • RE: AD8475 SPICE Macro-model error

    Hi Idan,

    Can you tell me what are you trying to do? Do you want to import the AD8475 on the specific simulation tool or platform? What simulation tool are you using? I believe the AD8475 should be available in Multisim and Simetrix.

    Best regards,

  • RE: Can AD8475 configured to a gain other than 0.4 & 0.8 using external resistors

    Hi Jebas,

    Thank you for question. Theoretically, the idea of using external resistors to adjust the gain of AD8475 should work. However, the internal resistors are laser trimmed to have the specified ratios, but the absolute values of these resistors…

  • Where should the -Vs pin of AD8475 be connected to?

    Hi, in the datasheet of AD8475, it says that the voltage supply can be +-5V and +VS can be connected to 5V while -Vs can be connected to -5V or AGND. However, during simulation, it reports an error of singular matrix when connect -VS to -5V. Moreover…

    Hello jpearson,mle,

    Thank you for the detailed explanation.
    AD8475 will also check.

    Thank you,again.
