Ground
Backside Paddle ⁴⁾
IC top marking: <P-CODE> = product code, <A-CODE> = assembly code (subject to changes);
1) Capacitive pin loads must be avoided when using the analog output signals.
2) Pin numbers marked n.c. are not connected.
3) The test pins TIP and TIN may remain unconnected. If connecting traces, ensure a proper ground level to avoid unwanted functions.
4) Connecting the backside paddle is recommended by a single link to GND. A current flow across the paddle is not permissible.
