I think its on Mark Hammer's Site as well 

[A.S.P.]

those are different ones

I haven't taken a look at the 36meg thing yet, but every BBD-related document out there seems to hold different tidbits, so snag it if you can.

As an aside, a tip.  there are various PDF creation packages out there, many of which allow you to use the "publish to pdf" function like you would use any printer.  One of the things this lets you do is call up a pdf document which is waaaaaaaaaaaay larger than what you need or are interested in, and print select sections to a secondary pdf document.  So, for instance, if you come across some manufacturer's service manual for a product, and all you really want is the schematic on pages 27 and 28, rather than the instructions, subject index, and warranty information at the end, you can open up the bigger file, and "print" pages 27-28 to a secondary PDF and save that on your drive, tossing away the larger file.

I mention this because it may be that only portions of the big Panasonic document may be useful.  Alternatively, you may want to save it to your drive as "chapters" devoted to specific devices or categories of devices.  This re-PDF-ing function lets you arrange the same information in the way you want.

Thank You for sharing this fine resource  .

Thanks Scott for the data.
Now, has anyone ever made/designed an analog reverb pedal with the MN3011 chip?
Was there ever a commercial verb pedal that used the chip?
Could be interesting, the only DIY verb I´m aware of is the femtoverb or something like that, digital, SMD chip...
Yeah, I know it´s an almost extinct chip, but the bear man still stocks it...
Just some thoughts

just search: 3011

BTW: thanks!, cd 

[Morocotopo]

Searched.
Found.
Grrrr!!!  I hate when the answer is "dude, cheaper/easier/whatever/ to buy a commercial one"... nothing to build...
A.S.P., you couldn´t let me dream for more than 10 seconds, could you?

To Mark Hammer and others:

Apparently the MN3305 pdf file around there is damaged somehow. At least from BBD Dementia file and Experimentalists Anonymous.  Acrobat Reader 7.0.9 indicates some problem with the file and won't open it.  On other sites the MN3305 is either missing or mentioned but not linked.  Does anybody have a working file for it?  (Not that I plan using one, just want it for completeness since I've got the rest of the MN33xx family datasheets).

Quite a few more can be found here. They used to have the big catalog, but seem to have taken it down for some reason. Its to bad, it had alot of info in it that applied to them all that is not in the single part data sheets.

http://www.synthdiy.com/datasheets.asp

Does anybody know what's this "extra" info about?

[Mark Hammer]

My first response was "Hmmm, I think I have that pdf file".  So I checked, and sure enough I do.  It looked kind of small (24k) so I tried booting it up, and sure enough it was a bad file that I must have gotten from synthdiy with a right-click save without ever checking it.  It would be nice to have, but quite frankly I have never in my life seen anything that used an MN3305, notr seen any place selling them, so it's not a great loss other than for archival purposes I suppose.

The original reason I went to look the MN3305 datasheet was:

1) In MN3005 applications the Clock driver IC (MN3101) has a diode in series with the most positive supply (GND in this case, since Vdd is assumed to be a negative supply).

2) In MN3205 applications the Clock driver IC (MN3102) has a diode in series with the most negative supply (GND again, since on these devices Vdd is assumed to be a positive supply).

3) Then, I wanted to see what the MN3305 had to say about this.

As you see, 1) and 2) use a diode in a different positions in the MN310x clock driver.  Then I noticed the MN30xx series are P-channel devices (intended for negative supply), where the MN32xx devices are N-channel devices intended for positive supplies, hence this explain the change in position for the clock driver diode.  If you want to further verify this in action, just check Boss schems for the following pedals: DM-2 (there are two versions, one with MN3005 and another with MN3205), DM-3, CE-2, CE-1, CH-1, DC-2, VB-2, etc.  No all of them use the diode, though.

So, all in all it makes sense in some way, however the reason for the "need" of said diode is not stated in the datasheets I've seen so far.  That was what I was trying to find out from the beginning    This is why I'd like to see a "real" application note on these BBD IC's, and not just an "application circuit" alone.

[A.S.P.]

can anyone open this file:

?

Cannot open it here.

Adobe 7 indicates an encryption plugin is required. It directs me to Adobe site but finally indicates it is not an Adobe supported plugin, so the author should be contacted to determine which plugin it is and where to get it (plugin: Filter/PSDS_Crypto)

Foxit Reader states "This document is encrypted by some unsupported security handler."

On a side note, so far I've found the RD5108A datasheet.  Are there a 5101 and/or 5106 datasheets available as well?
