Backside Paddle 4)
1) Capacitive pin loads must be avoided when using the analog output signals.
2) Pin numbers marked n.c. are not in use.
3) The test pins TIP and TIN may remain unconnected.
4) The backside paddle may have a single link to GND. A current flow across the paddle is not permissible.
