Perhaps NTE is ahead of the game, and indeed has a new source for these parts. Applications of the ca highperformance operational transconductance amplifiers an rev.
Note that you can achieve very respectable dynamic range with this part, and that it will operate on just a few xheet and with very little current.
Note that In desperate repair situations, some of the LM’s pins can be wired into a ‘ PCB pattern and provide identical results. Out of frusteration, I designed my own fill-in replacement for the ANP. 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, ca33080 sort of thing.
So here’s my recent email conversation with Intersil support on the matter: Knowing full-well that anything less thanwould not interest them, I didn’t pursue my case.
Use the LM; it’s not as good, but it’s still in production and second sourced. The process used to make those chips is very old and has been handed down through a number of corporate buyouts. There are not many alternatives available from other manufacturers. Thus, it is a voltage controlled current source vccs.
Data sheet dara file number datasheet catalog for. 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.
Neil Schubert at February 23, Of course I see that Texas Instruments is discontinuing it Is this a conspiracy.
I have had a problem with this chip for almost 11 years. Typical Performance Curves Continued.

But NJR obviously has a fab line capable of this “archaic” linear process. Too late; the plant somewhere in Ohio is gone, Intersil told me. Ca308 2mhz, operational transconductance amplifier ota,alldatasheet, datasheet, datasheet.
I’ll stick to my own circuit, due to the costant discontinuation of fixed ICs.
Today the wafer stock has been depleted to the point we have to withdraw the product. The guys who the fab was sold to? It’s a very different internal design, with very different characteristics, and it is used in dxta different way.
Texas instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 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 xa3080 mechanical systems, and so forth. As for other sources, I would start with our obsolete distributor, Rochester Electronics.
The ota or voltagecontrolled current source can be viewed as an ideal transistor. We have been living on wafer stock. 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. Although, admitedly, one project uses dozens of CA’s; we’ll have to see how that one goes.

This is also an opportunity to build a better discrete OTA. Widebandwidth, operational transconductance amplifier ota. The CA series parts are certainly cx3080 I think most of them were introduced before the Nixon administration!!! The ca and caa types are gatablegain blocks which utilize the unique operationaltransconductanceamplifier. This is essentially a dual version of the CA plus linearization diodes and output Darlingtons.
Applications of the ca highperformance operational. NTE must know that Intersil ran out of CAs, though, because the price has gone up about three-fold since I bought them. Operational transconductance amplifier ota and buffer 2.
BoxMail Stop The US is the largest exporter of industrial controls – which use lots of linear ICs. Ca 2mhz, operational transconductance amplifier ota from old datasheet system part no. The is invaluable in electronic music work. I am going to try to build it, and see if it works!
The ca is probably the most simple standalone cs3080 ota that you can.
