description: In the course of the work, the literature on circuit design, noise reduction, programming of GD32 series microcontrollers, interfaces for interaction with peripherals and literature on analog-to-digital converters, their classes and capabilities were studied. Open educational resources and information search and analysis programs were used. Automated development tools such as EasyEda were used. The Keil Î¼Vision 5 software has been applied. Because of the work, a circuit was developed that includes the main microcontroller, ADC, circuit elements for displaying information, filtering noise and ensuring a stable reference voltage. A code has also been developed that allows using the SPI bus to receive information from the ADC and using DMA to output information via UART using decimation with pre-filtering. This development can serve as the basis for sensitive devices that respond to voltage changes, and in measuring microelectronics, and based on the initial characteristics, it is possible to use the development for digitization and transmission of audio signals.
