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.
