Volume control ICs (Integrated Circuits) are not a specific brand but a category of electronic components used for audio signal amplitude adjustment. These ICs are produced by various global semiconductor companies, such as Texas Instruments (USA), Analog Devices (USA), NXP Semiconductors (Netherlands), and ON Semiconductor (USA). They serve industries like consumer electronics (headphones, speakers), automotive infotainment, and professional audio equipment. Key products include digital potentiometers, programmable gain amplifiers, and dedicated audio volume controllers with features like I²C interface and low distortion. These components are widely listed on industrial suppliers like Radwell and Grainger for automation and maintenance applications.
