Features
Overview

•
The ATmega16M1/32M1/64M1 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
from V
The reference voltage is the same as the one used for the ADC,
plexer Register” on page 242.
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 100mV and AVcc - 100mV
V
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 Ohm. So the driver is able to load a 1nF
capacitance in parallel with a resistor higher than 33K with a time constant around 1µs
