PSoC3 will rock as an audio power amp supervisory device!
Sorry to have been away from my blog for so long! I hope you've been following my Filter Wizard articles at EE Times Europe (http://www.eetimes.eu/en/News/filter-wizard.html). Before long, you'll get to see actual implementations of some of these filters on PSoC, as I hope to have access to a proper lab again to do the measurements.
Meanwhile, for the last few days I've been in San Francisco at the 129th Convention of the Audio Engineering Society, catching up with the latest technology and product trends in high quality and professional audio. Seeing the wide spread of equipment on show at the associated exhibition brought home just how useful our new PSoC3 devices will be in this space. Of course, all the micro guys can do a mix of buttons, lights and displays. But the programmable digital hardware of PSoC3 will give it a real edge for people who are doing custom signal and control interfaces, which abound in pro audio.
Audio amplification has always been a favourite subject of mine, and I'm also struck by what a good supervisory and control processor for amplifiers that PSoC3 will make. The flexible analogue capability can be deployed for voltage and current monitoring (of the amp and the psu), power device safe area protection and thermal management, and control of internal bias currents and voltages. Novel switchmode and hybrid power supply architectures can be developed and optimized for the particular application. Programmable logic enables no-code protection interlocks, and you can use the CAN bus to form a network between multiple amplifiers to ensure synchronized performance in high channel count systems. And for many applications, the audio signal processing, routing and management possible with UDB and DFB support will be more than sufficient.
All in all, I think this is a really exciting application and close to my heart, and I hope many of you out there will take up your DVK and your copy of PSoC Creator and develop something wonderful in the audio amplifier space!
