DAC main features

1.1

Overview

STM32 microcontrollers integrate DAC with different configurations and features:

•

1 to 3 DAC output channels

•

Noise waveform generation

•

Triangular waveform generation

•

DMA under run flag

•

Dedicated analog clock

Table 2 summarizes the different STM32 DAC configuration.
