4.2 Configuration 2: Single Conversion with 16x Gain

The second configuration features the ADC operating in Single Conversion mode, with the PGA enabled and the gain set to 16x. The same object weighing 2.003 kg is placed on the scale, and 300 ADC samples are recorded and analyzed.

As observed in Table 4-2, the weight of the object placed on the scale and the peak-to-peak error determined from the sampled data are in the same order of magnitude. Additional noise filtering is required to obtain an accurate weight measurement. The simplest and most convenient way to achieve this is to accumulate and average multiple ADC samples, which can be done in hardware, by operating the ADC in Burst Accumulation mode or in software by repeatedly accumulating single conversion results. The most notable advantage of the Burst Accumulation mode over software accumulation is the non-blocking aspect of it, as the ADC hardware peripheral performs the accumulation core independently.
