[sdiy] RMS converter schematics

[Justin Owen]

Hello,

I'm on the lookout for some schems that will take an AC signal (or one that has been full wave rectified) and output a 'true' RMS signal.

I have the Texas Instruments app note SNOA855 and a couple of versions of the DBX 160 RMS detector - but I was wondering if you lot could point me to or suggest any others.

Interested in anything from cheap and cheerful to pro.

Thanks,

- J
