[?]: Scale Function query

Post by waqas_here »

Please some one give me the reason why maximum binary weight of analog input (converted to digital by internal ADC) is always taken as 27648.
It should not be a fix value rather it should depend on the # of bits in the data is converted by ADC.
I know it is quite weird but it is some thing really bothering me these days.
