3.4 Analogue Power Supply Voltage (JP: 11, 13, 15)

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

provided internally or externally.

JP11, JP15 connect power supply voltages (AVcc and AVss)

JP13

connect reference voltages (AVRH to AVcc)

Jumper

JP11 (AVcc)

JP13 (AVRH)

JP15 (AVss)

By default the resistor-divider R11 and R23 is not mounted on the board

Default: JP11, JP13, JP15 are closed

By default, the A/D-converter supply and reverence voltage is +5V.

Note:

If JP11 and J15 are open, the user has to supply an adequate analogue voltage supply

(AVcc and AVss) to the A/D-converter.

If JP13 is open, the resistors R11 and R23 define AVRH. By default, the resistor divider (R11

and R23) is not mounted on the board.
