14. AC – Analog Comparator
14.1
2588E–AVR–08/10
Analog Comparator Multiplexed Input
The analog comparator compares the input values on the selectable positive pin (AIN0, AIN1 or
AIN2) and selectable negative pin (AIN0, AIN1 or AIN2). 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 com-
parator and its surrounding logic is shown in
Figure 14-1. Analog Comparator Block Diagram
Notes:
See
When the Analog to Digital Converter (ADC) is configurated as single ended input channel, it is
possible to select any of the ADC10:0 pins to replace the negative input to the analog compara-
tor. 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) is set and the ADC is switched off (ADEN in ADCSRA is zero), MUX5:0 in ADMUX
select the input pin to replace the negative input to the analog comparator, as shown in
14-1. If ACME is cleared or ADEN is set, either AIN0, AIN1 or AIN2 is applied to the negative
input to the analog comparator.
