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 50kΩ pull-up and pull-down resistors is very large. Actual value may range between 17 and 100kΩ.
