The Atmel
connected to an 8-channel Analog Multiplexer which allows eight single-ended voltage inputs
constructed from the pins of Port A. The single-ended voltage inputs refer to 0V (GND).
The ADC contains a Sample and Hold circuit 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
6-100 on page
The ADC has a separate analog supply voltage pin, AV
0.3V from V
pin.
Internal reference voltages of nominally 1.1V or AV
ence may be externally decoupled at the AREF pin by a capacitor for better noise
performance.
The Power Reduction ADC bit, PRADC, in
must be disabled by writing a logical zero to enable the ADC.
