Q2. On the AD4111/AD4112/AD4114/AD4115 can I detect if the input signals are floating due to faulty wiring?
AD4111 provides a unique solution for open wire detection on the voltage inputs from a single 5V/3.3V supply. Open wire detection is calculated by comparing the difference between the two-channel conversions to a certain threshold. Details can be found on page 27 in the Open Wire Detection section of the AD4111 datasheet.
