Hi Team

There is a resistor R2 between V33A and V33D in DS recommendation. 

I noticed it mentions that digital circuit will draw more current and generate more noise, and compared digital circuit, that analog circuit is more sensitive than digital. so if this resistor can de-couple the noise generated by digital circuit to analog circuit? Can you explain how this circuit impact the performance of UCD3138?
