Feature List

The ATmega163 features a 10-bit successive approximation ADC. The ADC is con-
nected to an 8-channel Analog Multiplexer which allows each pin of Port A to be used as
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 57.
The ADC has two separate analog supply voltage pins, AVCC and AGND. AGND must
be connected to GND, and the voltage on AVCC must not differ more than ±0.3V from
V
pins.
Internal reference voltages of nominally 2.56V or AVCC are provided On-chip. The
2.56V reference may be externally decoupled at the AREF pin by a capacitor for better
noise perfomance. See “Internal Voltage Reference” on page 29 for a description of the
internal voltage reference.
