Or something like that; I was napping at the time. Sync, Yeah, I know about that Then, they discontinued the ANP.

CA3094 Datasheet PDF

I have two of them at home but it may be easier to buy it here: The CA process was based on datasheeet old 7 micron specialized process. I actually researched that vatasheet. This is also an opportunity to build a better discrete OTA. While opamps are almost always implementing some function by the use of a specific feedback network, the OTA is very often used open loop or partially open loop.

That ebay item is from China. CA A N ca equivalent Abstract: Try to get other foundries to manufacture OTA chips.

By LeftyStrat in forum Guitar Effects. The CA improved on the performance of the CA through the, peak. NTE must know that Intersil ran out of CAs, though, because the price has gone up about three-fold since I dataheet them. Datasehet Posted by Enzo. Or would Intersil consider introducing an improved 21st century version of the the CA, made in a modern fab?

I’ll stick to my own circuit, due to the costant discontinuation of fixed ICs. There has been a lot of fearmongering from the electronic music crowd for a long time about electronic music parts going out of production. It’s been thirty years, man; surely we can make some improvements. Get it while you can.


CA / CAE DIP8 – Retroamplis

The closest thing to astill in production or recently enough is the LM and If you’re making a ‘s based synthesizer, you can use many different VCA circuits. We need to insure we have enough product remaining to support the life time buys that are now incoming. Note that In desperate repair situations, some of the LM’s pins can be wired into a ‘ PCB pattern and provide identical results.

They have very few selected parts, but the ones they do have usually datasheer. The is clearly the most advanced and flexible.

Not that the OPA isn’t an interesting chip I’m reading this with interest, as I built two synth VCAs that use the CA and I had to pick through a whole bunch of chips I originally bought way back in the ’80s. Peavey replaced the original part with LMN but that is now obsolete also.

What’s next, the ? Education is what you’re left with after you have forgotten what you have learned. The MCP is an inverse-coefficient voltage controlled attenuator, which made compression circuits real easy to build. And in that also where it mattered.

CA’ s for sale in batches of 50 on ebay, from Hong Kong just snatched up a bunch myself http: We have seen such things elsewhare, specially in the Audiophoolery world, but Peavey is a solid feet on the ground type of company, when they say specially selected I believe them, in this case being equivalent to “matched power transistors”, “selected for low noise Op Amps or transistors”, etc.


By the way does anyone know if there are pspice models for CA or ?? Looking at the Peavey schematic, I see that: There are not many alternatives available from other manufacturers. Most of these are somewhat antiquated designs and have few practical uses today.

I want to suggest that these chips are too important to retire. The time now is Adjustment of potentiometer R determines the magnitude of the regulated output.

They could just as easily left everyone hanging. I will pass on your concerns but datwsheet understand, these CA family of products were developed by RCA on a very old and obsolete fab dqtasheet that is long since been discontinued and the fab plant was shut down and sold off. Maybe this is why the chip industry is going to china! Originally Posted by g1. I didn’t look yet. Original Peavey part number is and the industry equivalent is CA
