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.

Internal reference voltages of nominally 1.1V or V

are provided On-chip.
