The AT90S4433 features a 10-bit successive approximation ADC. The ADC is con-
nected to a 6-channel Analog Multiplexer, which allows each pin of Port C to be used as
an 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 44.
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 from V
CC more than
±0.3V. See the section “ADC Noise Canceling Techniques” on page 70 for how to con-
nect these pins.
An external reference voltage must be applied to the AREF pin. This voltage must be in
the range 2.0 - AVCC.
