Yes, it can simplify any subsequent math used to process the signal.In looking through the datasheet for the MAX11100 ADC I noticed that it's spec'd with a 4.096V analog reference, which sets the input voltage range. Is there some benefit to an ADC input range being related to a binary value (2^12)?
In some applications is convenient to have have 1LSB equal to a nice even voltage.That sounds like it simplifies characterizing the device, but for normal use? Why would it matter if 1 LSB is 1.000mV or 1.1mv? Either way it's the same digital output value.
It's far easier perform calculations when interfacing an ADC referenced to that voltage to an MCU. Especially when dealing with assembly code and when very fast conversion rates are needed.That sounds like it simplifies characterizing the device, but for normal use? Why would it matter if 1 LSB is 1.000mV or 1.1mv? Either way it's the same digital output value.
