Overview
The ATmega164P/324P/644P features a 10-bit successive approximation ADC. The ADC is
connected to an 8-channel Analog Multiplexer which allows 8 single-ended voltage inputs con-
structed from the pins of Port A. The single-ended voltage inputs refer to 0V (GND).
The device also supports 16 differential voltage input combinations. Two of the differential inputs
(ADC1, ADC0 and ADC3, ADC2) are equipped with a programmable gain stage. This provides
amplification steps of 0 dB (1x), 20 dB (10x), or 46 dB (200x) on the differential input voltage
before the A/D conversion. Seven differential analog input channels share a common negative
terminal (ADC1), while any other ADC input can be selected as the positive input terminal. If 1x
or 10x gain is used, 8-bit resolution can be expected. If 200x gain is used, 6-bit resolution can be
expected. Note that internal references of 1.1V should not be used on 200x gain.
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 21-1
The ADC has a separate analog supply voltage pin, AVCC. AVCC must not differ more than
±0.3 V from V
CC. See the paragraph “ADC Noise Canceler” on page 251 on how to connect this
pin.
Internal reference voltages of nominally 1.1V, 2.56V or AVCC are provided On-chip. The voltage
reference may be externally decoupled at the AREF pin by a capacitor for better noise
performance.
