We are trying to interface ADG1436 as a built in test component for a k type amplifier circuit. For normal operation, there seems to be leakage current that flows at any point of time. No complete isolation. This affects the amplifier's gain and output.
Can ADG1436 used for precision measurement? Is there a way to completely isolate the switching?
We are simulating on TINA TI tool. Below are the attachment of the simulations.
