The ATmega8 features a 10-bit successive approximation ADC. The ADC is connected to an 8-
channel Analog Multiplexer which allows eight single-ended voltage inputs constructed from the
pins of Port C. 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
page
The ADC has a separate analog supply voltage pin, AV
from V
Internal reference voltages of nominally 2.56V or AV
ence may be externally decoupled at the AREF pin by a capacitor for better noise performance.
