Hi, I use 16-bit ADC to collect small-value ac signals, and then use USART to transmit them to the computer for reading. The following figures are the result I read. The amplitudes of the two signals are respectively 20mVpp and 100mVpp, and we can ...

Thanks for your anwser. In the fixed version, the value of R1 and R2 is fixed. And I want to know the exact value of resistance to calculate the impact of LDO access on the impedance my circuit.RegardsZhang

Thanks for your answer. But I still have a few questions. Firstly, in a continuous sampling process, ADC can maintain the sampling rate of 16-bit for most of the time, but the sampling rate of ADC will be seriously reduced from 16-bit to 10-11-bit at...
