Overview
ATtiny5/10 feature an 8-bit, successive approximation ADC. The ADC is connected to a 4-channel analog multi-
plexer which allows four single-ended voltage inputs constructed 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 13-1 on page 83.
Internal reference voltage of V
CC is provided on-chip.
The ADC is not available in ATtiny4/9.
13.3
Operation
In order to be able to use the ADC the Power Reduction bit, PRADC, in the Power Reduction Register must be dis-
abled. This is done by clearing the PRADC bit. See “PRR – Power Reduction Register” on page 26 for more
details.
The ADC is enabled by setting the ADC Enable bit, ADEN in “ADCSRA – ADC Control and Status Register A”.
Input channel selections will not go into effect until ADEN is set. The ADC does not consume power when ADEN is
cleared, so it is recommended to switch off the ADC before entering power saving sleep modes.
The ADC converts an analog input voltage to an 8-bit digital value using successive approximation. The minimum
value represents GND and the maximum value represents the voltage on V
CC.
The analog input channel is selected by writing MUX1:0 bits. See “ADMUX – ADC Multiplexer Selection Register”
on page 92. Any of the ADC input pins can be selected as single ended inputs to the ADC.
The ADC generates an 8-bit result which is presented in the ADC data register. See “ADCL – ADC Data Register”
The ADC has its own interrupt request which can be triggered when a conversion completes.
