Heck, the original Moog modulars were all discrete. It has an OTA and a buffer so seems perfect for filters. Perhaps NTE is ahead of the game, and indeed has a new source for these parts.
They’re shooting themselves in the foot! The ca and caa are similar in generic form to conventional operational. Surface mount does not belong on an airplane or in a car!

I predict that if the CA is not discontinued, sales will pick up as the supplies of the other OTA chips drop off and the choice of which OTA to use narrows, with the resurgance of audio and electronic music applications, and with new applications being developed. Applications of the ca highperformance operational transconductance amplifiers an rev. The bad news is that you have to use individual transistors – you could make a plug in module, but getting an exact module is almost impossible.
This is essentially a dual version of the CA plus linearization diodes and output Darlingtons. 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. Accordingly, the reader is cautioned to verify that data sheets are current before placing orders.
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.

Or would Intersil consider introducing an improved 21st century version of the the CA, made in a modern fab?
Dual operational transconductance amplifier the au and ne contain two currentcontrolled. None of the other chips comes close in these areas, so if you can only support one OTA chip, that’s the one.
Pond at May 20, The operational transconductance amplifier ota is an amplifier whose differential input voltage produces an output current. Data sheet april file number datasheet catalog for. Current applied to the amplifierbiascurrent terminal, iabc, establishes the emitter current of the input differential ampli. I tried, too, to persuade Intersil to keep at least the CA, which I ca33080 often.
CA’ s for sale in batches of 50 on ebay, from Hong Kong just snatched up a bunch myself http: Art Harrison at September sheet, We are now reviving and old product that used theand have found some datx supplies.
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? We have been living on wafer stock. Try to get other foundries to manufacture OTA chips. No license is granted by implication or otherwise under any patent or patent rights daata Intersil or its subsidiaries.
Knowing full-well that anything less thanwould not interest them, I didn’t pursue my case. Thus, it is a voltage controlled current source vccs. The market size for the CA part just will not return a profit for the cost.
Now you can comment. I might do that; it could 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. The stupidity of the IC industry is that they neglect to understand that the VCA is c3080 function that does not work well in digital. Use the LM; it’s not as good, but it’s still in production and second sourced.

Do you know if another company like the one that purchased the old fab equipment is considering carrying on cs3080 when the current stock depletes? Ne dual operational transconductance amplifier. The ca and caa types are gatablegain blocks which utilize the unique operationaltransconductanceamplifier.
It was discontinued the year I designed the boards, and by the time I had made my first prototype built, I had to re-design again.
Ca operational transconductance amplifier components datasheet pdf data sheet free from sheeet data sheet search for integrated circuits ic, semiconductors and other electronic components such as resistors, capacitors, transistors and diodes.
As for other sources, I would start with our obsolete distributor, Rochester Electronics. However, no responsibility is assumed by Intersil or its subsidiaries for its use; nor for any infringements of patents or other shret of third parties which may result from its use. Today the wafer stock has been depleted to the point we have to withdraw the product. But the OTA’s are a serious loss. The CA process was based on an old 7 micron specialized process.
