I have 2 quick questions. 1. What is the ON resistance and capacitance of AMUX and AMUX Sequencer?. 2. What is the Sampling Resistance and Capacitance of SAR and Delta Digma ADC?

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.
