6 Conclusion

To conclude the analysis performed in this document, the development of the showcased weight scale or similar applications that require low-voltage signal measurement would not be possible without using an amplification stage before sampling. The ADC peripheral with integrated PGA provides an effective and low-cost solution compared to external amplifiers. Among other advantages, the PGA firmware selectable gain and input multiplexing allow for the development of a wide variety of applications, including multiple channels data acquisition systems, as the usually limited number of dedicated amplification pins is no longer a constraint. If additional noise reduction is required, Burst Accumulation mode can be used to improve the accuracy of the measurement.
