20. AC - Analog Comparator
20.1
Overview
The Analog Comparator compares the input values on the positive pin AIN0 and negative pin
AIN1. When the voltage on the positive pin AIN0 is higher than the voltage on the negative pin
AIN1, the Analog Comparator output, ACO, is set. The comparator’s output can be set to trigger
the Timer/Counter1 Input Capture function. In addition, the comparator can trigger a separate
interrupt, exclusive to the Analog Comparator. The user can select Interrupt triggering on com-
parator output rise, fall or toggle. A block diagram of the comparator and its surrounding logic is
shown in Figure 20-1
The Power Reduction ADC bit, PRADC, in “PRR – Power Reduction Register” on page 47 must
be disabled by writing a logical zero to be able to use the ADC input MUX.

Notes:
2. Refer to Figure 1-1 on page 2 and Table 12-5 on page 80 for Analog Comparator pin
placement.
20.2
Analog Comparator Multiplexed Input
It is possible to select any of the ADC7..0 pins to replace the negative input to the Analog Com-
parator. 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), MUX2..0 in ADMUX
select the input pin to replace the negative input to the Analog Comparator, as shown in Table
20-1 on page 240. If ACME is cleared or ADEN is set, AIN1 is applied to the negative input to the
Analog Comparator.
