Feature list:
0945I–AVR–02/07
The ATmega103(L) features a 10-bit successive approximation ADC. The ADC is con-
nected to an 8-channel Analog Multiplexer, which allows each pin of Port F to be used
as an input for the ADC. The ADC contains a Sample and Hold Amplifier, which ensures
that the input voltage to the ADC is held at a constant level during conversion. A block
diagram of the ADC is shown in Figure 45.
The ADC has two separate analog supply voltage pins, AV
be connected to GND, and the voltage on AV
V
these pins.
An external reference voltage must be applied to the AREF pin. This voltage must be in
the range AGND - AV
