Analog to Digital Converter - ADC

SUB-20 has 8 single ended and a 16 differential analog input combinations with x1 x10 or x200 input gain amplifier. Analog inputs are referenced as ADC0..ADC7 see GPIO Header. The SUB-20 ADC module features a 10-bit successive approximation ADC. The ADC contains a Sample and Hold circuit which ensures that the input voltage to the ADC is held at a constant level during conversion.
