Hello, All! I am trying to design a PI metal detector. I need some advice on what to do with unused I/O pins on a quad analog switch. I need to use two sections of DG411. Now, I know that I could parallel 2X2 gates to use all four sections, but for the sake simplifying the PCB layout I would prefer not.
My question is: would it be OK to tie unused "D" pins together and unused "S" pins together - and then ground "D" or "S" through a 10k resistor, or is there a better way of dealing with this?
I would appreciate any advice.
With best regards, Brett Holden. E-mail: snipped-for-privacy@bellsoh.net Forgot the t in south
