title: STMicroelectronics STM32 DAC

description: |
  The STM32 DAC is a 12-bit voltage output digital-to-analog converter. The DAC
  may be configured in 8 or 12-bit mode. It has two output channels, each with
  its own converter.
  It has built-in noise and triangle waveform generator and supports external
  triggers for conversions. The DAC's output buffer allows a high drive output
  current.
