Example of external network sizing
The following hypothesis is formulated in order to proceed with designing the external net-
work on A/D converter input pins:
1.
2.
3.
4.
Now, the three elements of the external circuit R
discussed in the previous paragraphs have been used to size the component; the others
must now be verified. The relation which allows to minimize the accuracy error introduced by
the switched capacitance equivalent resistance is in this case:
So the error due to the voltage partitioning between the real resistive path and C
Analog signal source bandwidth (f
Conversion rate (f
Sampling time (T
Pin input capacitance (C
Pin input routing capacitance (C
Sampling capacitance (C
Maximum input current injection (I
Maximum analog source voltage (V
Analog source impedance (R
Channel switch resistance (R
Sampling switch resistance (R
Supposing to design the filter with the pole exactly at the maximum frequency of the
signal, the time constant of the filter is:
Using the relation between C
it is possible to define C
As a consequence of Step 1 and 2, RC can be chosen:
Considering the current injection limitation and supposing that the source can go up to
12V, the total series resistance can be defined as:
from which is now simple to define the value of R
