4.3 Configuration 3: Burst Conversion with 16x Gain

The third configuration features the ADC operating in Burst Conversion mode with 1024 accumulation samples. The PGA is enabled, and the gain is set to 16x. The same object used in the previous configurations is placed on the scale, and 300 burst conversion results are recorded and analyzed.

Operating the ADC in Burst Accumulation mode makes a significant improvement in the accuracy of the measurement compared to the second configuration. The hardware accumulation and averaging process improves the noise reduction, as seen in the previous chart. When compared to the Single Conversion mode, the drawback of the Burst Accumulation mode is the longer conversion time, which depends on the configured number of accumulation samples.
