Thanks for your help in advance. I have two somewhat related questions:
1. The 9958 has a ground slug on the backside. The data sheet says this must but attached to ground but fails to mention which ground: analog or digital?
2. Previously I saw either an AD application note or posting on this forum about driving both Analog and Digital supply ports using a single shared supply with reasonably good results. For the life of me I can't find this anymore. Can you direct me to this information?
