Backside Paddle
Pin numbers marked n.c. are not in use. The backside paddle is not intended as an electrical connection point;
when used as shield a single link to GND is permissible. The test pins TIP and TIN may remain unconnected.
Capacitive pin loads must be avoided when using the analog test signals for alignment purposes.
