USB-3114: Analog Input Isolation

[JWS]

I have a test setup where I will be using the USB-3114 analog output to drive and ADC input. This same input also has the ability to provide 10VDC as an output. When the 10VDC is turned on will the USB-3114 input be damaged? Is there any internal isolation on the USB-3114 analog output?

The USB-3114 analog output is provided by an AD8510 op amp and driving the output can cause damage. If there's another signal also connected to the ADC, then it best to make some sort of interlock circuit that disconnects one while the other active.
