I have the ADG712 designed into a board such that the NC pin (pin 4) is connected to ground. I have just noticed that the datasheet says "Do not connect to this pin". I'd appreciate any comments on this e.g. is this going to damage the part?
Pin 4 and 12 in the ADG712 are not internally connected to the die so connecting it to ground should cause no damage to the device.
Thanks Stephen - that's the answer I was hoping for
