ADS1115: Gain drift spec interpretation

Part Number: ADS1115


I'm looking at the datasheet for this item and need some help in the interpretation of the "long-term gain drift" spec. I am trying to calculate how this spec would translate into a change in the ADC output over time.

The datasheet says this spec is +-0.05%.

Lets say I have the FSR set to the default of +-2.048 V, and my input signal is 0V. I get an output code of 2^15. Later the gain drifts by the specc'ed -+0.05%.  Does this mean my output code will be:

2^15 +- 2^16*0.0005 = 2^15 +- 32

Thank you very much!
