Processor integrates audio peripherals for infotainment, stand-alone consumer audio

Analog Devices announced an audio-centric addition to its SigmaDSP processor line that exceeds the signal processing capabilities of earlier SigmaDSP devices. Improvements in hardware and software enable the ADAU1452 SigmaDSP processor to execute up to three times more audio processing algorithms than its predecessors, providing system designers with more flexibility to improve the audio performance of their products. The processor features a unique hardware architecture that is optimized for efficient processing of audio signal flows created using the company’s SigmaStudio graphical programming tool. The ADAU1452 is the first product in the SigmaDSP family of audio processors to allow both time-domain and frequency-domain processing simultaneously. This extends the range of signal processing techniques that can be implemented to solve system design problems. The ADAU1452 is suited to a variety of products in applications such as automotive infotainment (amplifiers and head units), consumer audio (soundbars, sub-woofers and active speakers), and professional audio (amplifiers, mixers and effects units).

Analog Devices, Inc. was founded by two MIT graduates, Ray Stata and Matthew Lorber in 1965. The same year, the company released its first product, the model 101 op amp, which was a hockey-puck sized module used in test and measurement equipment. In 1967, the company published the first issue of its technical magazine, Analog Dialogue.
