1. What is the ON resistance and capacitance of AMUX and AMUX Sequencer?.

   

 

   

From the device datasheet -

   

 

   

   

2. What is the Sampling Resistance and Capacitance of SAR and Delta Digma ADC?

   

 

   

Input SAR R is in device datasheet or component datasheet. Same is true for DelSig.

   

 

   

Use the ohmmeter tool in analog view tab *.cydwr file workspace explorer for evaluating mux

   

resistance.

        Dana, Thanks for your reply. Btw, what's the different with following attached snapshot?. I found it in "GPIO DC Specifications" section. One more thing, what is the impedance of Vref pin (e.g: P0[3])? I think it is the noninverting input of the Op Amp. I want to know whether I need to put Buffer on it or not.
