The ATtiny13 features a 10-bit successive approximation ADC. The ADC is connected
to a 4-channel Analog Multiplexer which allows four single-ended voltage inputs con-
structed from the pins of Port B. The single-ended voltage inputs refer to 0V (GND).
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 40.
