ADS1298: input impedance measurement

Part Number: ADS1298

hi,

do you have any advice on how to accurately measure the DC input impedance of ADS1298/98R with all the external components directly on the PCB?

thanks a lot in advance

    Hello Vincenzo,

    Thanks for your post. Is your customer trying to pass the IEC standards certification for input impedance, similar to this post? 

    These IEC standards apply to the system level design. The customer will have to purchase and understand the IEC standards as they validate and certify their design. The ADS1298/98R has adequate input impedance to allow them to meet this standard per the data sheet specificiation.

    Best regards,
