I'm using the AD820 in a loop filter in an RF circuit and I would like to maximize the ground plane area. Can the "NC" pins on the AD820 (SOIC-8) be grounded without ill effects? I am also using the ADP151 voltage regulator. Since the datasheet for the ADP151 states that the NC pin is "not connected internally" I am grounding it. The datasheet for the AD820 describes the null pins (two of the three NC pins) as being nonfunctional in the SOIC-8, but it is not clear whether they can be grounded.
