A digital to analog converter (DAC) is a device with a function opposite to that of an analog to digital converter, i.e. it converts a digital word to a corresponding analog voltage. The STM32 DAC module is a 12-bit word converter, with up to three output channels to support audio functions.
microcontroller - Picking a DAC for an audio amplfier ...
https://electronics.stackexchange.com/questions/17001/picking-a-dac-for-an-audio-amplfier
The amplifier allows both differential or single audio source inputs and I'd like the DAC to work with 0 to 5V TTL inputs from 16 pins of the microcontroller. I think 16 bit should be the appropriate size of the DAC but there are so many to choose from. If anyone has a good tutorial on using a DAC for audio generation from a microcontroller I'd ...
Audio DAC: STM32
https://jonathan.engineer/posts/audio-dac-stm32/
Option: Replacing the USB-2-I2S chip w/a microcontroller …other things like actually receiving the audio packets via USB and outputting them to the DAC via I2S. So let’s see what this might look like. One downside is that a microcontroller has a decent amount of dependencies (e.g. crystals, capacitors, bootloaders, etc) that I had hoped to ...
audio - 16 bit DAC microcontroller - Electrical ...
https://electronics.stackexchange.com/questions/403566/16-bit-dac-microcontroller
I'm currently working on a audio project where I need to play a 16 bit depth signal with a speaker. Right now I'm using an atmega328 for prototyping, two 8 bit shift registers (controlled by the MCU) and an R-2R DAC (and an LM386). Given that the setup is not so simple, I was wondering if an MCU with a 16 bit DAC exists.

A microcontroller (& programmer if required). An active buzzer module / speaker. Jumper wires. A 220Ω resistor. A breadboard. A Basic Introduction to Digital Audio. So what is audio/so u nd? In the simplest terms, the sensation of sound is a result of vibrations in the air caused by pressure fluctuations.

Generating Sinewave using DAC and 8051 Microcontroller. For generating sinewave, at first we need a look-up table to represent the magnitude of the sine value of angles between 0° to 360°. The sine function varies from -1 to +1. In the table only integer values are applicable for DAC input.
