The AT90PWM81 features a 10-bit Digital to Analog Converter. This DAC can be used for the analog
comparators
The DAC has a separate analog supply voltage pin, AV
V
The reference voltage is the same as the one used for the ADC,

ence may be externally decoupled at the AREF pin by a capacitor for better noise performance.
CC
10 bits resolution
8 bits linearity
+/- 0.5 LSB accuracy between 100mV and AVcc-100mV
Vout = DAC*Vref/1023
The DAC could be connected to the negative inputs of the analog comparators and/or to a dedicated output
driver.
Output impedance around 1KOhm.
