Note
1. All supply connections must be made to the same power supply.
2. Short-circuit test at Tamb = 0 °C and VDDA = 3 V. DAC operation after short-circuiting cannot be warranted.
10 HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, it is good practice to take
normal precautions appropriate to handling MOS devices.
