CA3080 PDF

ca Transconductance Amplifiers are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for ca Transconductance. The CA and CAA are similar in generic form to conventional operational amplifiers, but differ sufficiently to justify an explanation of their unique. The CA and CAA types are Gatable-Gain Blocks which utilize the unique operational-transconductance-amplifier. (OTA) concept described in.

It might actually work for my dozens-of-OTA’s project. I think that the ANP was ca3800 designed for television sets, which needed volume to be remote-controlled.

Don’s Blog: Last of the OTA’s

Concerned electronic music folks could make “lifetime buys” and do fine. Ok, enough ranting and raving. The is also capable of functionally replacing any of the other OTA models, ignoring the obvious pin-compatibility issues.

NTE seems the best hope. We are now reviving and old product that used theand have found some ca300 supplies. So here’s my recent email conversation with Intersil support on the matter: The guys who the fab was sold to? Use the LM; it’s not as good, but it’s still in production and second sourced. The is clearly the most advanced and flexible.

But the output is a current source instead of a voltage source. This was not a big deal. NTE must know that Intersil ran out of CAs, though, because the price has gone up about three-fold since I bought them. Dear Don, I will pass on your concerns but please understand, these CA family of products were developed by RCA on a very old and obsolete fab process that is long since been discontinued and the fab plant was shut down and sold off.

Now you can comment. Too late; the plant somewhere in Ohio is gone, Intersil told me.

Rochester – CA3080AE IC – Reissued OTA Chip

I have had a problem with this chip for almost 11 years. Yeah, I know about that Maybe this is why the chip industry is going to c3a080 What’s next, the ? I am going to try to build it, and see if it works! Or better yet, an even higher quality OTA!

Thanks for signing in.

The transistor arrays are certainly nice, but given how easy it is to hand-match transistors, I don’t see an array of less-than-great transistors on a chip as an especially compelling story. I’ll be happy to consult on such ca300 project. If you want, the MCP has a well drawn internal circuit.

Out of frusteration, I designed my own fill-in replacement for the ANP. By the way does anyone know if there are pspice models for CA or ?? Do you know of any date codes to avoid with the Harris or Intersil parts? It’s been thirty years, man; surely we can make some improvements.

Note that In desperate repair situations, some of the LM’s pins can be wired into a ‘ PCB pattern and provide identical results. Thanks for passing my comments on. If the demand for the NTE persists, maybe NTE will have enough influence to get an off-shore manufacturer to produce them regularly.

Try to get other foundries to manufacture OTA chips. Sync, Yeah, I know about that OTA’s are general purpose devices, not specific to electronic music applications, so the demand should be enough to support at least one good one.
