Specifications
• Input voltage range: 0 V ... 10 V
• Input resistance: 4 k
• ADC resolution: 12 bit
The input signals are referenced to PC ground GND.
Note
• Actually, the ADC add-on board even provides a
third 10 V analog input ANALOG IN2 with
identical specifications (also see
input values of this third analog input is not
queryable via read_analog_in.
