The ATmega169 features a 10-bit successive approximation ADC. The ADC is con-
nected 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 device also supports 16 differential voltage input combinations. Seven differential
analog input channels share a common negative terminal (ADC1), while any other ADC
input can be selected as the positive input terminal.
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 Figure 82.
The ADC has a separate analog supply voltage pin, AVCC. AVCC must not differ more
than ± 0.3V from V
connect this pin.
Internal reference voltages of nominally 1.1V or AVCC are provided On-chip. The volt-
age reference may be externally decoupled at the AREF pin by a capacitor for better
noise performance.
