58.3 External Analog Reference Connections

The following schematic checklist is only necessary if the application is using many of the external analog references. If the internal references are used instead, the circuits in the following two figures are not necessary.

Table 58-2. External Analog Reference Connections
Signal Name	Description	Recommended Pin Connection
VREFx	External reference VREFA/VREFB/VREFC	Capacitors⁽²⁾: refer to REG_9⁽¹⁾
AVSS	Ground	-

Note:

Refer to the “Power Supply Electrical Specifications” from the Electrical Characteristics chapter.
Decoupling capacitors must be placed close to the device, low ESR capacitors must be used for better decoupling.
