But NJR obviously has a fab line capable of this “archaic” linear process. Ask a Question Want to reply to this thread or ask your own question? If the demand for the NTE persists, maybe NTE will have enough datasheeh to get an off-shore manufacturer to produce them regularly. The newly created question will be automatically linked to this question. Margin,quality,low-cost products with low minimum orders.

Nah; more like a very weird chip that didn’t sell. Please create an account or Sign in. I don’t blame Intersil.

CAE (Intersil) – 2MHz, Operational Transconductance Amplifier (OTA), Operational Amplifiers

The CA series parts are certainly old; I think most of them were introduced before the Nixon administration!!! 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. The solution you propose would work, but from a matching pespective, you should use 2x OPA with a linearisation resistor in between. Datasjeet was not a big deal.

We need to insure we have enough product remaining to support the life time buys that are now incoming. The CA process was based on an old 7 micron specialized process.


Of course not the same pinout but then you get 2 x CA in a package.

I tried, too, to persuade Intersil to keep at least the CA, which I use often. So here’s my recent email conversation with Intersil support on the matter: TI, its suppliers and providers of content reserve the right to make corrections, deletions, modifications, enhancements, improvements and other changes to the content and materials, its products, programs and services at any time or to move or discontinue any content, products, programs, or services without notice.

Do you know of any date codes to avoid with the Harris or Intersil parts?

Jul 2, And I’m sure the CA hasn’t been their top seller. It has an OTA and a buffer so seems perfect for filters. I am designing a high order analog filter for the audio range. The LM has been discontinued.

Content on this site may contain or be subject to specific guidelines or limitations on use. You can’t dynamically compress or expand in digital without generation of rounding noise Faithfully describe 24 hours delivery 7 days Changing or Refunding. But the OTA’s are a serious loss.

Use the LM; it’s not as good, but it’s still in production and second sourced. Hi Andree, Thank you for your feedback. I want to use this one because they have a Pspice model so I can model it all in software, and TI still is selling this currently. The is invaluable in electronic music work. There are not many alternatives available from other manufacturers. Go to Support forums.

Using Operational Transconductance (Voltage-to-Current) Amplifiers

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. You’ll need to choose a username for the site, which only take a couple of moments here. Any help would be appreciated! Of course I see that Texas Instruments is discontinuing it Is this a conspiracy.

Eventually, I figured out how to make a cancelation circuit, and my VCA is now in the testing stages. All content and materials on this site are provided “as is”. I have a datasheet for the CA, but Googling for equivalents is not being very helpful.

The MCP is an inverse-coefficient voltage controlled attenuator, which made compression circuits real easy to build. Post a comment Thanks for signing in.

No license, either express or implied, by estoppel or otherwise, is granted by TI. See their cross reference: Use of the information on this site may require a license from a third party, or a license from TI. The supplier usually indicates equivalent products within their range, however, on this case they have no suggestions! Heck, the original Moog modulars were all discrete. Jul 20, What I really want is a replacement for the high end CA OTA’s are perfect for a multitude of electronic music applications because they can control a parameter, such as amplifier gain or filter frequency, and control it very accurately over a range of at least three decades.

The stupidity of the IC industry is that they neglect to understand that the VCA is one function that does not work well in digital. NTE seems the best hope. This time I had to use an LM and a resistor current circut to make the inversion for the compressor. Some manufacturers have cross references online.
