Hello

Please let me know about Ron of multiplexer. in AD7091R-8.

For example,  the datasheet of  AD7329 which the device is like AD7091R-8 ( Muxout -> ADC in) describes  below

  MUXOUT+ Capacitance (datasheet P. 6)

  Resistance including  on resistance of multiplexer (Datasheet P.20)

I can not find above parameter in datasheet of AD7091R-8.

Please let meknow your advice.
