I am designing an anemometer for university project. I intend to use analog switches to switch between ultrasonic sensors. I use this circuit as my first stage - it adds offset to the signal and has high-pass filter. The input signal is centered around 0V I want to know if this could be a problem for the switch I am going to be using the signal not that large (tens of millivolts).
I have also read about charge injection and I learned that it is inversely proportional to the load capacitance I am not really sure if it's going to be a problem or not in this case.
This is the datasheet of the switch I plan to use : http://www.ti.com/lit/ds/symlink/ts3a5018.pdf
