Digital-to-analog converters (DACs) are not a specific brand but a category of electronic devices used to convert digital signals into analog signals. These devices are produced by various companies worldwide, including industry leaders like Texas Instruments (USA), Analog Devices (USA), and Maxim Integrated (USA, now part of Analog Devices). DACs serve critical roles in industries such as audio equipment, telecommunications, industrial automation, and consumer electronics. Key products include high-precision DACs for industrial control systems, audio DACs for premium sound systems, and integrated DAC modules for embedded applications. Manufacturers often provide a range of DACs with varying resolution, speed, and interface options to meet diverse technical requirements.
