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.
Let me check on this. I'll get back to you soon.
The on resistance of the multiplexer with a 5 V supply is typically 50 ohms, while with a 2.5 volt supply the on resistance typically increases to 100 ohms. This is outside of the resistance mentioned on page 19 of the datasheet. By the way, the bandwidth of the system (1.5 MHz) has been verified through the entire signal chain.
Hope this helps.
Thank you for your support.
