Re: Buck converter for CVDD?

Thanks for the replies! Hannu, The potentially bad effects that a buck converter might have on the analog section has crossed my mind. Testing would be in order. I was certainly expecting to have to beef up all the decoupling caps. It hadn't crossed my mind to tie the CVDD inputs to both the interna...

Buck converter for CVDD?

Hello, I'm starting on the design of my PCB using the VS1005, and have been thinking about potentially using a buck DC-DC converter for CVDD, as that seems to be where the greatest power efficiency gain would be over a linear regulator. Maybe I missed it, but I have not seen mention of it in any doc...

Re: Headphone driver short circuit monitoring?

Thanks for the response, Panu. I did indeed see the low value resistors in some of the dev board schematics. In my case, it would be kind of handy if the driver section shut down, but it sounds like I might not be able to rely on that happening. Maybe instead I can send a test DC signal to the right...

Headphone driver short circuit monitoring?

Hello all! I am slowly getting acclimated with all things VS1005 (lots to learn here!), while simultaneously making some design decisions. I have a potential concern with my project where a mono line level plug may inadvertently get inserted into headphone jack, shorting the ring to the sleeve. I do...

Re: Requesting clarifications on VS1005 capabilities..

Thank you, Panu. I'll be sure to ask more narrow questions as I study the problems some more.

Thanks,
Mark

Re: Requesting clarifications on VS1005 capabilities..

Panu, Thank you for your brisk response, and I apologize for my own delay. I have gone down the rabbit hole, so-to-speak, with regards to desired functionality and searched high and low for solutions from various vendors just to come full circle back to VLSI's very compelling offerings. I've become ...

Requesting clarifications on VS1005 capabilities..

Hello VLSI staff and fellow members, Maybe this is an obvious question, but gleaning over some of the available documentation as well as forum thread subjects, I found nothing on the topic, so I will ask here: Can the VS1005 simultaneously record one (or more) stream(s) while playing back another to...
