4.2.2 Analog Power Supply

These devices have a separate analog supply pin AVDD for future compatibility. In this device, the AVDD and VDD power domains are internally connected.

The following figure shows the recommendation for connecting a power supply to the AVDD pin of the device.

Figure 4-2. Recommended AVDD Connection Circuit Schematic
Important: For systems that frequently cycle VDD or experience fast VDD transients, it is recommended to add an additional decoupling capacitor (C3) if the power supply slew rate exceeds the slew rate limits. Refer to the Supply Voltage section in the Electrical Characteristics for details about power supply slew rate limits.
