Analog Comparator Inputs
Analog Compare Positive Input
ADC Multiplexer
The Analog Comparator compares the input values on the positive pin (AIN1) and negative pin
(AIN0). When the voltage on the positive pin is higher than the voltage on the negative pin, the
Analog Comparator output, ACO, is set. The comparator can trigger a separate interrupt,
exclusive to the Analog Comparator. The user can select Interrupt triggering on comparator
output rise, fall or toggle. A block diagram of the comparator and its surrounding logic is shown
in
Figure 18-1. Analog Comparator Block Diagram
Notes:
It is possible to select any of the inputs of the ADC Positive Input Multiplexer to replace the
positive input to the Analog Comparator. The ADC multiplexer is used to select this input, and
consequently, the ADC must be switched off to utilize this feature. If the Analog Comparator
Multiplexer Enable bit (ACME in ADCSRB register) is set and the ADC is switched off (ADEN
in ADCSRA register is zero), MUX[4:0] in ADMUX register select the input pin to replace the
positive input to the Analog Comparator, as shown in
is set, AIN1 pin is applied to the positive input to the Analog Comparator.
