Today the wafer stock has been depleted to the point we have to withdraw the product. It’s the preferred chip for voltage controlled oscillators, voltage controlled filters, voltage controlled amplifiers, waveform shaping, modulation, signal processing, routing and control, chaos circuits, simulation of mechanical systems, and so forth. For data on series CMOS IC pinouts use the generic code like leave out the letters form the beginning and end of the code The search engine can also tell what markings like 2R2, 1u1, 3p3 etc.

There is also data and cross reference for very many battery types. It is possible to increase the linearity of the OPA to any accuracy required, the trade-off by doing so is the reduction of the Gm and possibly an increase in noise. I have had a problem with this chip for almost 11 years. Don Tillman at November 10, The CA process was based on an old 7 micron specialized process. Now you can comment. 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.

Using Operational Transconductance (Voltage-to-Current) Amplifiers

I almost went to using the CA, but had problems with its manufacturer, Harris, who was datzsheet “competitor” in the broadcast industry at the time.

Try to get other foundries to manufacture OTA chips. We are glad that we were able to resolve this issue, and will now proceed to close this thread.


Hi Andree, Thank you for your feedback. I don’t blame Intersil. If no information is available those sections are empty. Thanks for signing in.

I predict that if the CA is not discontinued, sales will pick up as datasheeet supplies of the other OTA chips drop off and dstasheet choice of which OTA to use narrows, with the resurgance of audio ratasheet electronic music applications, and with new applications being developed. Concerned electronic music folks could make “lifetime buys” and do fine. I am designing a high order analog filter for the audio range. I might do that; it datashewt have a lower noise input stage, built in exponential conversion for the programming current, a better linearization circuit, better current mirrors, that sort of thing.

It has an OTA and a buffer so seems perfect for filters. Should you find an inaccuracy, or have additional product data to add that you feel would improve this tool, please forward the information to webmaster epanorama.

Use the LM; it’s not as good, but it’s still in production and second sourced. OTAs in general, please refer to Application Notes: Interdigitation, or crosscoupling, of critical portions of the circuit reduces the amplifier dependence upon thermal and processing variables. It might actually work for my dozens-of-OTA’s project. No warranty is expressed or implied regarding the accuracy of this data. We recommend that you completely review datasheet to confirm the device functionality for your application.

Then, they discontinued the ANP. Eventually, I figured out how to make a cancelation circuit, and my VCA is now in the testing stages. The is also capable of functionally replacing any of the other OTA models, ignoring the obvious pin-compatibility issues.

I’ll stick to my own circuit, due to the costant discontinuation of fixed ICs. All content and materials on this site fatasheet provided “as is”. Electronics component information search at www. There is also pinout for very many ICs and transistors. S AN, and AN You can get wire data with keyboards like 12AWG and 1. It features a very nice input diode linearization circuit, low noise, low offset voltage, and it comes in matched pairs.


The component information data database knows over most common transistors, diodes, logic ICs and many other components. Dwtasheet 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. Ok, enough ranting and raving. It’s been thirty years, man; surely we can make some improvements. Nah; more like a very weird chip that didn’t sell.

I tried, too, to persuade Intersil to keep at least the CA, which I use often.

So, my fellow analog enthusiasts, I suggest that you ratasheet NJR for the ‘, ‘, and their like, if your quantity requirements are large enough to make it worth their while. Heck, the original Moog modulars were all discrete. And I’m sure the CA hasn’t been their top ratasheet. Along those lines, the is inspirational for new designs.

If you’re making a ‘s based synthesizer, you can use many different VCA circuits. Do you know of any date codes to avoid with the Harris or Intersil parts? Due to the holidays, responses may be delayed. The process used to make those chips is very old and has been handed down through a number of corporate buyouts. Use of the information on this site may require a license from a third party, or a license from TI.

The solution you propose would work, but from a matching pespective, you should use 2x OPA with a linearisation resistor in between. For one, there are a lot of CA’s still available, maybe hundreds of thousands, and that should meet demand for a while. These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
