DAC:Equipment for Converting Digital Data to Analogue Signals
https://maker.pro/micropython/projects/dacequipment-for-converting-digital-data-to-analogue-signals
DACs can accurately reconstruct sampled data into analog signals. Digital data can be generated by microprocessors, Application Specific Integrated Circuits (ASICs), or Field Programmable Gate Arrays (FPGAs), but the final data needs to be converted to an analog signal in order to interact with the real world.
