2812 Numerical calculation of collected analog quantities [Copy link]

How come I see the calculation formula in the material is: Digital Value = 4095 **Input Analog Voltage -ADCLO)/3.0
but I also see

((float)AdcRegs.ADCRESULT0)*3.0/65520.0 = Input Analog Value
But why is it 65520.0 instead of 4095?
Please advise.

A little wrong, should be divided by 2^16-2^4,
