Refer to power-supply considerations in application information for selection of appropiate capacitors on supply inputs.

The diagram refers to the 16-pin DB package. It is recommended that the 3 AVCC pins be tied together externally to minimize power loss. For
the 20-pin package, the 4 AVCC pins (13, 14, 15, and 16) must be tied together externally as close as possible to the device.
