The CA process was based on an old 7 micron specialized process. The process used to make those chips is very old and has been handed down through a number of corporate buyouts. OTA’s are perfect for a multitude of electronic music applications because they can control a parameter, such as amplifier gain or filter frequency, and control it very accurately over a range of at least three decades.
The MCP is an inverse-coefficient voltage controlled attenuator, which made compression circuits real easy to ca300e. OTA’s are general purpose devices, not specific to electronic music applications, so the demand should c3a080e enough to support at least one good one.
Most of these are somewhat antiquated designs and have few practical uses today. Art Harrison at September 23, It’s been thirty years, man; surely we can make some improvements. Don Tillman at July 16, It has an OTA and a buffer so seems perfect for filters.
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.
So here’s my recent email conversation with Intersil support on the matter: Go to Support forums. Max Output Power dxtasheet Channels Load: So, we reluctantly must withdraw these CA parts as our stock is depleted and in good faith, notify our customer base in time for last time buys. Current – Input Bias: The CA series parts are certainly old; I think most of them were introduced before the Nixon administration!!! Content on this site may contain or be subject to specific guidelines or limitations on use.
But the OTA’s are a serious loss. Mar 7, 2. Of course I see that Texas Instruments is discontinuing it Is this a conspiracy. They’re shooting themselves in the foot! Mar 8, 3. Concerned electronic music folks could make “lifetime buys” and do fine. CAE equivalent sought Reply to Thread. TI is a global semiconductor design and manufacturing company.
There are many audio electronics applications for theand while admitedly most audio is digital now, the analog alternatives are where the high-end markets lie.
Ask a new question Ask a new question Cancel. Do you know of any date codes to avoid with the Harris or Intersil parts? 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.

This is also an opportunity to build a better discrete OTA. In reply to Xavier Ramus:. Maybe this is why the chip industry is going to china!
Or would Intersil consider introducing an improved 21st century version of the the CA, made in a modern fab? For audio applications, the SSM works well. SeekIC only pays the seller after confirming you have received your order. Do you have another question? And I’m sure the CA hasn’t been their top seller. Sync, Yeah, I know about that In reply to Andree Henkel:. Along those lines, the is inspirational for new designs. Note that you can achieve very respectable dynamic range with this part, and that it will operate on just a few volts and with very little current.

Try to get other foundries to manufacture OTA chips. 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. Voltage – Input Offset: Datasheeet think that the ANP was originally designed for television sets, which needed volume to be remote-controlled.
