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
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)? 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.
