TDA7442 STMicroelectronics | Digitally Controlled Audio Processor - AICCHIP

Product Overview: TDA7442

The TDA7442 is a high-performance, digitally controlled audio processor designed by STMicroelectronics for high-fidelity audio systems, including legacy TV sets and Hi-Fi equipment. It features four stereo inputs, input attenuation control in 0.5dB steps, and comprehensive I²C-bus controlled tone (bass and treble) and balance functions. A key highlight is the integrated surround sound processor, which uses a programmable phase shifter to create immersive "Music" or "Simulated Stereo" effects. While the TDA7442 is officially Obsolete (EOL), it remains a critical component for the maintenance of high-end legacy audio signal chains and consumer electronics worldwide.
