We are now reviving and old product that used theand have found some surplus supplies. The is invaluable in electronic music work. There are not many alternatives available from other manufacturers. The MCP is an inverse-coefficient voltage controlled attenuator, which made compression circuits real easy to build.

Thanks for signing in. Download or read online rochester electronics caa 2mhz, operational transcondictance amplifier ota slew rate pdf data sheet. NTE must know that Intersil ran out of CAs, though, because the price has gone up about three-fold since I bought them.

CA Datasheet, PDF – Alldatasheet

Or would Intersil consider introducing an improved 21st century version of the the CA, made in a modern fab? Or better yet, an even higher quality OTA!

So, my fellow analog enthusiasts, I suggest that you wheet NJR for the ‘, ‘, and their like, if your quantity requirements are large enough to make it worth their while. This is also an opportunity to build a better discrete OTA. If you want, the MCP has a well drawn internal circuit.


Ca datasheet, cross reference, circuit and application notes in pdf format. Not that the OPA isn’t an interesting chip The ca and caa types have differential input and a. For audio applications, the SSM works well. 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 shert forth.

CA3080E – CA3080 Transconductance Amplifier Datasheet

OTA’s are not complex devices, although a substantial amount of hand matching of transistor will be required, but that’s not difficult. Wide bandwidth operational transconductance amplifier. Would this be equivalent or better then AE for audio range?

Operational cz3080 amplifier ota and buffer 2. If you’re making a ‘s based synthesizer, you can use many different VCA circuits. Ca 2mhz, operational transconductance amplifier ota from old datasheet system part no.

Widebandwidth, operational transconductance amplifier. I’ll be happy to consult on such a project. The ota employs only active devices transistors and diodes. I don’t blame Intersil.

CA3080 Datasheet

This was not a big deal. Most of these are somewhat antiquated designs and have few practical uses today. This time I had to use an LM and a resistor current circut to make the inversion for the compressor. 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. Perhaps NTE is ahead of the game, and indeed has a new source for these parts.

Don’s Blog: Last of the OTA’s

Art Harrison at September 23, And I’m sure the CA hasn’t been their top seller. 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. We have been living on wafer stock. 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.


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.

NTE seems the best hope. You can’t dynamically compress or expand in digital without generation of rounding noise Until then, it won’t appear on the entry. I tried, too, to persuade Intersil to keep at least the CA, which I use often.

We need to insure we have enough product remaining to support the life time buys that are now incoming. Note that In desperate repair situations, some of the LM’s pins can be wired into a ‘ PCB pattern and provide identical results. Yeah, I know about that
