ADS115 input capacitor

[neilh10]

Feature Request : For analog inputs can a capacitor or capacitor pad be added to the analog input.
The data sheet ads1113 Fig 49 layout shows the ideal of a low pass RC, but maybe this adds to much cost to the cct.
Typically to create the lowest S/N the analog has its own ground, and then tied to the digital ground in one place along the route the I2C signals travel.
"Sect 9.3.2 The ADS111x use a switched-capacitor input stage" , so there is a current pulse every time the internal capacitor is applied to the pad.
