I'm planning to design an external ADC 16:2 multiplexer board for the two channel 12-bit 1MSPS ADC on the XADC Minized Zynq I have seen in the schematic that I can access the AD0P, AD0N, AD8P and AD8N ports from the headers for the Arduino Shield, the pins ARDUINO_A2, ARDUINO_A3, ARDUINO_A4, ARDUINO_A5 The ARDUINO_A2 pin is only connected to the Zynq Bank 35 but ARDUINO_A3 and ARDUINO_A4 are both connected to the gate of two BSS138 N-CHANNEL MOSFET for controlling the bi-element PL-LED. As I will use both input channels as unipolar those pins will be connected to GND. The ARDUINO_A5 is connected to the DIP PL switch, so I think I can switch off that switch. My question is if what I'm thinking is safe and can I use those ports with that configuration? ARDUINO_A3 -> GND ARDUINO_A4 -> GND SW1 -> OFF -> GND

Help with XADC Minized ports for ADC External Multiplexer

I'm planning to design an external ADC 16:2 multiplexer board for the two channel 12-bit 1MSPS ADC on the XADC Minized Zynq

I have seen in the schematic that I can access the AD0P, AD0N, AD8P and AD8N ports from the headers for the Arduino Shield, the pins ARDUINO_A2, ARDUINO_A3, ARDUINO_A4, ARDUINO_A5
The ARDUINO_A2 pin is only connected to the Zynq Bank 35 but

ARDUINO_A3 and ARDUINO_A4 are both connected to the gate of two BSS138 N-CHANNEL MOSFET for controlling the bi-element PL-LED. As I will use both input channels as unipolar those pins will be connected to GND.
The ARDUINO_A5 is connected to the DIP PL switch, so I think I can switch off that switch.

My question is if what I'm thinking is safe and can I use those ports with that configuration?
