说明：  以Sigma-Delta ADC芯片为代表的过采样ADC技术，其采样频率可以远高于信号带宽的两倍，进而来提高模数转换器的分辨率，而且其易于实现低电压和低功耗。对于当今快速发展的可穿戴设备、人工智能AI以及物联网电子产品的续航要求提供了较好的解决方案
(The over-sampling ADC technology represented by sigma-delta ADC chip can increase the resolution of the ADC by far more than twice the signal bandwidth, and it is easy to realize low voltage and low power consumption. It provides a better solution for the battery life requirements of today's rapidly developing wearable devices, artificial intelligence AI and Internet of things electronic products)
