The ATmega16/32/64/M1/C1 features a 10-bit Digital to Analog Converter. This DAC can be
used for the analog comparators and/or can be output on the D2A pin of the microcontroller
via a dedicated driver.
The DAC has a separate analog supply voltage pin, AV
±0.3V from V
this pin.
The reference voltage is the same as the one used for the ADC,
ter – CLKPR” on page
voltage reference may be externally decoupled at the AREF pin by a capacitor for better noise
performance.
10 bits resolution
8 bits linearity
+/- 0.5 LSB accuracy between 150mV and AVcc-150mV
Vout = DAC*Vref/1023
The DAC could be connected to the negative inputs of the analog comparators and/or to a
dedicated output driver.
The output impedance of the driver is around 100 Ohms. So the driver is able to load a 1nF
capacitance in parallel with a resistor higher than 33K with a time constant around 1us.
