3.3 Analogue Power Supply Voltage

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

provided internally or externally.

JP2, JP8

connects analogue power supply voltages (AVcc and AVss)

JP3

connects the analogue reference voltage AVRH to AVcc

Jumper

JP2 (AVcc)

JP3 (AVRH)

JP7 (AVss)

Default: grey

Table 3-4: Jumper settings for Analogue Power supply

By default the resistor network (R8, R11) is not mounted on the board

By default, the A/D-converter supply and reference voltage is same as the microcontroller

supply voltage.

Setting

Description

Closed

AVcc is connected to Vcc

Open

AVcc is disconnected from Vcc

Closed

AVRH is connected to AVcc

Open

AVRH defined by resistor network

Closed

AVss is connected to GND

Open

AVss is disconnected from GND

Note:

If JP2 and JP7 are open, the user has to supply an

adequate analogue voltage supply (AVcc and AVss) to

the A/D-converter.

If JP3 is open, the resistors R8 and R11 define AVRH.

By default the resistor network (R8, R11) is not

mounted on the board.
