Hello all,
I have confusion in ADC of STM32L471 datasheet parameters.
1. ADC clock frequency(fADC)=80 MHz --------what is this and where is its application in ADC
2. Sampling rate for FAST channels(fs)=5.33Msps for 12bit --------what is this and where is its application in ADC
3. External input impedance (RAIN)=50Kohm--------what is this and where is its application in ADC
4. Internal sample and hold resistor(RADC) = ?? what is this and how to decide its value
5. Internal sample and hold capacitor(CADC) =5pF --------what is this and how to decide its value
6. Sampling time(ts)= 8.00625 µs --------what is this and how to decide its value
7. Total conversion time(tCONV)= 8.1625 what is this and how is its calculated
Thanks in advance !!!
