1 Applies to gain ≤ 1, impedance refers to ACH<0..3>–
2 Applies to gain > 1, impedance refers to ACH<0..3>–
AI/DIO = Analog Input/Digital I/O, DO = Digital Output, pd = pull-down, pu = pull-up
The tolerance on the 50 k Ω pull-up and pull-down resistors is very large. Actual value may range between 17 and 100 kΩ.
