... Second, stray capacitance at the input terminal is 1.1k minimized which in turn increases signal bandwidth. In the header or can package, the case of the AD645 is connected to V OUT Pin 8 so that it may be tied to the input potential (when operat- ing as a follower) or tied to ground (when operating as an in- verter). The AD645’ ...
