Other Parts Discussed in Thread: OPA859, OPA858
I am trying to design a selectable gain stage using the OPA657 and an analog switch.
I want to have 5 gain stage and a wide bandewitdh (up to 20MHz).
But, the cds capacitance of the analog switch decreases the performances of the system.
Do anybody have a solution to handle the problem of the CDS capacitance of the switch?
