Hi!
I have a related question to [FAQ] What is Charge Injection?
Does it mean if MUX works only on a resistive load the charge rejection will affect only internal MUX capacitance?
For example for TMUX1574 when we apply 3 volts on the MUX input and turn on the switch, charge injection will be approximately 3.5 pC and the ON capacitance Con for TMUX1574 is equal 7.5 pF:
dVout = 3.5 pC / 7.5 pF = 0.47 V.
So, we will have 3.47 V on the output, when it is 3 V on the input.
