    PSOC 4 Datasheet

    user_14586677

      In the PSOC 4 datasheet the CM input range for SAR is stipulated as

         

      Vss to Vdda, should it be Vssa to Vdda ?

         

       

         

      Also in TRM no discussion mentioned if SAR is a R ladder solution. Reason

         

      I ask is the linearity specs are only speced for Vref >= 1 V, but if architecture

         

      is R ladder one would think much lower Vrefs would still experience the same

         

      linearity performance ? Or is this related to switch performance in the ladder

         

      mux to decision comparator ?
