MN3007 equivalent schematic

[lightningfingers]

I noticed on some of TIs datasheets, they include equivalent shematics for ICs, and I know some manufacturers used to make discrete opamps.....theres a few in my roland funnycat...
Is there one for the MN3007 in existence? I wonder how hard it would be to make a BBD from discrete components..

You sure could.  An MN3007 has 1024 stages, so you'd need 1024 MOSFETs and capacitors, along with a bunch of other parts.  Pretty neat they can stuff all that into a tiny chip, huh?

[puretube]

they did that with TUBES, in the old days...  (not 1024 stages, though...)

Oh.  :|

Its very neat that they get all them MOSFETs in 1 chip. I had actually considered making one, but after clocking up how much 1024 MOSFETs would cost, the $10 from small bear doesn't seem too bad :lol:
Apart from that I couldn't even find a datasheet for the MN3007...

Hi Martin,

Mark Hammer has the definitive collection of BBD datasheets zipped up in a file call "bbdementia.zip".  Just google for bbdementia and you'll find it.  It contains the MN3007 datasheet, amongst a host of others.

Also, a complete scanned booklet from Panansonic with a plethora of info on all the MN30XX BBD's can be found here:

this is neater!

The PowerPC G5 microprocessor has over 58 million transistors on it and it incorporates IBM's 90 nanometre (0.09 micrometre) fabrication process. That's 1/1000th the diameter of a human hair.

W  :shock:  W

Thats incredible...

Scott: thanks i'll check that out
