A/D and D/A converters - Basic concepts and parameters
D/A and A/D converters work in two opposite directions. The former (also known as DAC , i.e. digital-analog ) allow the generation of constant or variable voltages (sometimes also currents) based on the numbers fed to them in binary form. In turn, analog-to-digital converters (also A/D or ADC converters) convert continuous (analog) signals into digital form, i.e. numbers corresponding to the input voltages (or currents) on a specific scale. Each converter is characterized by the number of bits that determine the resolution (e.g. an 8-bit converter supports 28, i.e. 256 levels of analog signal). In addition to resolution, AC converters are described by many other parameters, including: sampling speed (e.g. 1 kSps means 1000 samples/second), input (output) voltage range and power supply, number of channels and noise level. The conversion of an analog signal into a digital one is carried out in a simple way that is useful for an electronics engineer.
D/A and A/D converter - As many applications, as many converters
It is clear that there is no single type of transducer suitable for all possible applications . In simple measurement or control devices, 8- or 10-bit transducers are often sufficient, but in precise measurement or audio systems, 16-, 18- and even 24-bit transducers are required. While audio converters (both A/D and D/A) are characterized by quite high sampling rates of 44 kSps or more, specialized measurement converters with the same resolution usually operate at much lower speeds, but offer a much higher accuracy and very low noise. In some systems, multi-channel transducers are highly desirable, e.g. when two, four, or even a dozen or so analog channels need to be measured simultaneously (or alternately). An analog-to-digital converter is equipment available in various options for various specialized applications .
A/D and D/A converters available at the Botland store
You can find an AC or CA converter as part of more complex modules. Our offer includes a number of universal modules containing A/D and D/A converters, which are perfect for both measurement and control systems, as well as high-quality audio devices. We offer the now iconic PCF8591 systems containing 8-bit A/D and D/A converters in the form of modules, containing - in addition to the converter itself - also the necessary power supply circuits and connectors, enabling convenient connection with the target system. We also have caps with 16-bit A/D converters, designed to work with Raspberry Pi minicomputers, and high-class hat caps, equipped with A/D and D/A converters with 24- and 16-bit resolutions. Here you will also find several transducer models sold as single integrated circuits, e.g. MCP3204 or MCP3008. A digital-to-analog converter is basic electronic equipment used by professional electronics engineers and hobbyists.
