Overview
The ATmega169P 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 F. 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 Figure 22-1
The ADC has a separate analog supply voltage pin, AVCC. AV
CC must not differ more than
卤0.3V from V
CC. See the paragraph 鈥滱DC Noise Canceler鈥� on page 222 on how to connect this
pin.
Internal reference voltages of nominally 1.1V or AVCC are provided On-chip. The voltage refer-
ence may be externally decoupled at the AREF pin by a capacitor for better noise performance.
The Power Reduction ADC bit, PRADC, in 鈥漃(p谩n)RR 鈥� Power Reduction Register鈥� on page 45 must
be written to zero to enable the ADC module.
