This isn't a matter of cost, but a matter of maintaining a consistent

A brief look into the datasheet shows that the chip is a generic adc. So
I assume its use is not limited to voltage monitoring, and that you
would in fact expect to change the gain during runtime (ie not only at
system startup). Is this a correct assumption ?
