The market size for the CA part just will not return a profit for the cost. 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.

Wide bandwidth operational transconductance amplifier ota. Thus, it is a voltage controlled current source vccs. This is also an opportunity to build a better discrete OTA. Semiconductor november ca, caa 2mhz, operational transconductance ampli.

Ota ca3080 datasheet pdf

It has an OTA and a buffer so seems perfect for filters. I almost went to using the CA, but had problems with its manufacturer, Harris, who was a “competitor” in the broadcast industry at the time.

As dta other sources, I would start with our obsolete distributor, Rochester Electronics. Until then, it won’t appear on the entry. The CA series parts are certainly old; I shet most of them were introduced before the Nixon administration!!!

Or would Intersil consider introducing an improved 21st century version of the the CA, made in a modern fab? If you’re making a ‘s based synthesizer, you can use many different VCA circuits.


CA Datasheet pdf – 2MHz, operational transconductance amplifier (OTA) – Harris Semiconductor

Out of frusteration, I designed my own fill-in dat for the ANP. The is also capable of functionally replacing any of the other OTA models, ignoring the obvious pin-compatibility issues. Maybe this is why the chip industry is going to china! The LM has been discontinued.

I have a question. Most of these are somewhat antiquated designs and have few practical uses today. None of the other chips comes close in these areas, so if you can only support one OTA chip, that’s the one.

Texas instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. You can’t dynamically compress or expand in digital without generation of rounding noise Do you know of any date codes to avoid with the Harris or Intersil parts? Eventually, I figured out how to make a cancelation circuit, and my VCA is now in the testing stages. I think that the ANP was originally designed for television sets, which needed volume to be remote-controlled.

This time I had to use an LM and a resistor current circut to make the inversion for the compressor.

PDF CA3080 Datasheet ( Hoja de datos )

It features a very nice input diode linearization circuit, low noise, low offset voltage, and it comes caa3080 matched pairs. Post a comment Thanks for signing in. Because the transconductance of an ota operational. 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.

CA Datasheet(PDF) – Intersil Corporation

Widebandwidth, operational transconductance amplifier ota. We have been living on wafer stock. No license is granted by implication or otherwise under any patent or patent rights of Intersil or its subsidiaries. Concerned electronic music folks could make “lifetime buys” and do fine. So here’s my recent email conversation sata Intersil support on the matter: The ota section of the ne is identical to the lm NJR wanted to know my annual usage of dtaa ‘ If you want, the MCP has a well drawn internal circuit.


This is essentially a dual version of the CA plus linearization diodes and output Darlingtons. Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. BoxMail Stop Ok, enough ranting and raving. Yeah, I know about that Ca datasheet, cross reference, circuit and application notes in pdf format.

Ne dual operational transconductance amplifier. Thanks for passing my comments on. Nah; more like a very weird chip that didn’t sell. Don Tillman at July 16, Small and compact means unreliable and unserviceable. However, no responsibility is assumed by Intersil or its subsidiaries for its use; nor for any infringements of patents or other rights of third parties which may result from its use. You can use all semiconductor datasheet in alldatasheet, by no fee and no register.

Typical Performance Curves Continued. It’s an amplifier; and like an opamp it has a pair of differential inputs and a single output. We have problem to buy CAM But the output is a current source instead of a voltage source. But NJR obviously has a fab line capable of this “archaic” linear process.
