The ATmega16/32/64/M1/C1 features a 10-bit successive approximation ADC. The ADC is
connected to an 15-channel Analog Multiplexer which allows eleven single-ended input. The
single-ended voltage inputs refer to 0V (GND).
The device also supports 3 differential voltage input amplifiers which are equipped with a pro-
grammable gain stage, providing amplification steps of 14dB (5x), 20 dB (10x), 26 dB (20x), or
32dB (40x) on the differential input voltage before the A/D conversion. On the amplified chan-
nels, 8-bit resolution can be expected.
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
18-1.
The ADC has a separate analog supply voltage pin, AV
±0.3V from V
this pin.
Internal reference voltages of nominally 2.56V or AV
erence may be externally decoupled at the AREF pin by a capacitor for better noise
performance.
