CA3080 Datasheet PDF

Because the transconductance of an ota operational. The ota employs only active devices transistors and diodes. A c a a c a ae c a am a ca am 96 a c a e c a m c a, pinouts sheeet m e tal ca n to p view note.

The CA series parts are certainly old; I think most of them sheeet introduced before the Nixon shret We are now reviving and old product that used theand have found some surplus supplies. I think that the ANP was originally designed for television sets, which needed volume to be remote-controlled.

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.

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 don’t blame Intersil.

Thanks for signing in. Texas instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. Widebandwidth, operational transconductance amplifier. However, no responsibility is assumed by Intersil or its subsidiaries for its use; nor for any infringements of daga or other rights of third parties which may result.


Pond at May 20, The is invaluable in electronic music work. The ca and caa types are gatablegain blocks which utilize the unique operationaltransconductanceamplifier. Cz3080 ota or voltagecontrolledcurrent source can be 1features.

Try to get other foundries to manufacture OTA chips. These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. I am going to try sheer build it, and see if it works!

Or better yet, an even higher quality OTA! It’s a very different internal design, with very different characteristics, and it is used in a different way. James Gideon at November 9, In summary, I think it would be a big win to keep the CA in production, for all the standard business reasons, but also because the chip is culturally and educationally important, and it would give Intersil a great repuation.

Out of frusteration, I designed my own fill-in replacement for the ANP. And then after acquiring buying Burr Brown, Texas Instruments has to figure out what to do with all that stuff they got. But NJR obviously has a fab line capable of this “archaic” linear process. Let’s raise the bar a little, shall we? BoxMail Stop Today the wafer stock has been depleted to the point we have to withdraw the product.

Most of these are somewhat antiquated designs and have few practical uses today. Somebody picking up the ?


Thanks for passing my comments on. Maybe this is why the chip industry is going to china! 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. Perhaps NTE is ahead of the game, and indeed has a new source for these parts. OTA’s are perfect for a multitude of electronic music applications wheet they can control a parameter, such as ac3080 gain or filter frequency, and control it very accurately over a range of at least three decades.

The datasheet consequently claims constant impedance bu. For audio applications, the SSM works well. By the way does anyone know if there are pspice models for CA or ?? We need to insure we have enough product remaining to support the life time buys that are now incoming.

Concerned electronic music folks could make “lifetime buys” and do fine. And there is currently a resurgance in modular analog music synthesizers SynthTech, Synthesizers. Now you can comment.

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. I have a number of projects and articles in the pipeline that use CA’s, and I’ll keep on course with those.
