Voltage appearing on C18 during precharging process
The voltage appearing on the capacitor C13 connected to pin 20 is shown in the following
figure. It can be seen that due to the fact that it is charged by a constant current source
it exhibits is a linear increase in voltage which is limited to U
= 2.5V which is also the
Smax
approximate operating point of the data filter input. The time constant appearing in this
case can be denoted as T
