Capacitance Cds(on)

Hello,

 

we are using two Multiplexer/Switches ADG1404,ADG1436 to change measurement ranges in an application. While measuring low currents we use a high resistance of about 1MOhm to convert the current into a voltage. The problem that occurs is, that the Capacitance Cds(on) together with the resistance leads to a lowpass-filter with a very low corner frequency.
Is there a way to compensate the internal Capacitance of the switch?

 

Thanks in advance
Kind regards

Ronny
