The AT90PWM2/2B/3/3B features a 10-bit successive approximation ADC. The ADC is con-
nected 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 2 differential voltage input combinations which are equipped with a
programmable 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 Figure 21-1.
The ADC has a separate analog supply voltage pin, AV
CC. AVCC must not differ more than ±
0.3V from V
CC. See the paragraph “ADC Noise Canceler” on page 241 on how to connect this
pin.
Internal reference voltages of nominally 2.56V or AV
CC are provided On-chip. The voltage refer-
ence may be externally decoupled at the AREF pin by a capacitor for better noise performance.
