[STM32L] ADC channels and sampling rate

Hi all.

In the datasheet and reference manual,  it mentioned STM32L1xxRx has 1 ADC module with 20 channels.  I know that 12-bit resolution, the maximal sampling rate could be up to 1Msps.

My question is, if I use 5 analog I/O channels,  how would the sampling rate of each channel be?  Would it be 1Msps for each I/O or it should be divided by the factor of 20 (or 5?)

I'm not very familiar with how the ADC channels work.  Hope someone here could help.

Thanks, :)
