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