IC top marking: <P-CODE> = product code, <A-CODE> = assembly and lot code (subject to changes);
1) Pin numbers marked n.c. are not connected.
2) The backside paddle may have a single link to GNDA. A current flow across the paddle is not permissible.
Wiring unused input pins can be recommended depending on the selected operating mode (EPG), especially for pins TPS, TNS, TPC, TNC (e.g. via 10 kΩ to
GNDA).
