3.3 Analog Power Supply Voltage (JP: 9, 8, 10)

The power supply as well as the positive reference voltage for the A/D-converter can be

provided internally or externally.

JP3, JP7

connects analog power supply voltages (AVcc and AVss)

JP5

connects the analog reference voltage AVRH to AVcc

Jumper

JP9 (AVcc)

JP10 (AVRH)

JP8 (AVss)

By default the resistor network (R4, R6) is not mounted on the board

Default: JP9, JP10 and JP8 are closed

By default, the A/D-converter supply and reference voltage is connected to VCC3V3 (3.3V)

Note:

If JP8 and JP9 are open, the user has to supply an adequate analog voltage supply (AVcc

and AVss) to the A/D-converter.

If JP10 is open, the resistors R4 and R6 define AVRH.

By default the resistor network (R4, R6) is not mounted on the board.
