The AT90S8535 features a 10-bit successive approximation ADC. The ADC is con-

nected to an 8-channel Analog Multiplexer that allows each pin of Port A to be used as

an input for the ADC. The ADC contains a Sample and Hold Amplifier that ensures that

the input voltage to the ADC is held at a constant level during conversion. A block dia-

gram of the ADC is shown in Figure 45.

The ADC has two separate analog supply voltage pins, AVCC and AGND. AGND must

be connected to GND and the voltage on AV

CC must not differ more than ±0.3V from

V

CC. See “ADC Noise Canceling Techniques” on page 74 on how to connect these pins.

An external reference voltage must be applied to the AREF pin. This voltage must be in

the range 2V - AV

CC.
