I've got offset voltages of 0,2V with a device containing ADG333ABNZ. Do the pin compatible newer versions like ADG1434 or ADG5434 correct this?
Offsets usually appear when the analog switches are used in high impedance environments (Mohms) and it is mainly caused by leakage currents or charge injection.
While leakage is always present…
I found out that the offset has nothing to do with the analog switches. It only appears if the signals are connected to an unpowered NI-6216 DAQ. If the device is powered up or the signal is not connected, everything is allright.
Anyway thank you for your help!
