When there is a discrete solution, there is often complex routing that needs to be done to ensure noise isolation between the analog and digital signals. In order to shield the noise, the designer has to include shield signals which increases the routing by three times the number of traces for each signal. In order to isolate for noise, longer traces are often needed. This increases both the routing complexity as well as the size and cost of the board. Also several revisions of the board may be needed to debug noise issues. With an Intelligent Analog solution, this complexity is removed by having the analog integrated inside the PIC MCU. The PCB layout is much easier with fewer traces and lower noise coupling. Shorter more direct traces help increase noise robustness. All of this integration and simplification in routing leads to a much smaller board size and hence a lower system cost. In addition, since the PCB is simpler, it makes the prototyping process faster with fewer board revisions required.
