I'm planning to interface the output from a pressure sensor such as this one, to an ADC pin on a PIC16F1823. The advantage is that both devices work at 5V, and the sensor delivers a signal varying between 0.5 and 4.5V, according to its specs. Now, the PIC16L1823 ADC has a 10 bit resolution, and since the sensor will be working within 80% of the total 5V range of the ADC, I expect this will result in measurements spanning 819 divisions, approximately. Which is more than enough for my application.
Question, should an RC filter such as shown below be placed between the sensor's output and the ADC pin?
If using this sort of filter is recommended, what values would be considered typical for this sort of application?
