    PSoC 5 Designer AD DA converter

    qqiuu
              I have a question regarding AD DA converter used in PSoC Designer 5.0. For chip CY8C29466, what is the most suitable types of ADC use to change analog signal from a operational amplifier in AD DA converter?

          Welcome in the forum, Qqiuu.

             

          You are here in the wrong forum, the PSoC5 has no connection to Designer 5, you are asking a question for a PSoC1.

             

          When designing an ADC (Analog-to Digital Converter) some facts must be evaluated first.

             

          Input signal range: must be (or must be converted to) GND < Vin < VCC

             

          Desired frequency

             

          Wanted resolution

             

          The last two points influence each other: Better resolution takes more time for converting.

             

           

             

          Besides: I would suggest you to upgrade your Designer 5.0 to latest version which is 5.4.

                Whoops! Is the above post an echo from the end of www? Could be interesting to interpret the run-time as a function of web-size.

                  One word of caution, pay particular attention to the signal path CM Range,

                     

                  it can / cannot be R-R performance depending on what you are doing. You

                     

                  can connect an A/D directly to pins w/o going thru an opamp or PGA if so

                     

                  desired.
