The ota or voltagecontrolled current source can be viewed as an ideal transistor.

If the demand for the NTE persists, maybe NTE will have enough influence to get an off-shore manufacturer to produce them regularly. But the OTA’s are a serious loss. These types also have a high output impedance and hseet transconductance g M is directly proportional to the amplifier bias current I ABC. 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. Usually it’s just a case of some guys who are naturally kind’a jumpy.

In addition, these types have an amplifier bias input which may be used either for gating or for linear gain control.

CA3080E – CA3080 Transconductance Amplifier Datasheet

NTE seems the best hope. Ca308 devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. I have had a problem with this chip for almost 11 years. What I really want is a replacement for the high end CA Do you know of any date codes to avoid with the Harris or Intersil parts? Or something like that; I was napping at the time.


The is invaluable in electronic music work. The ota section of the ne is identical to the lm I am designing a high order analog filter for the audio range.

Not that the OPA isn’t an interesting chip Now you can comment. And I have a significant number of additional applications in the pipeline.

Cx3080 the output is a current source instead of a voltage source. If you’re making a ‘s based synthesizer, you can use many different VCA circuits. This time I had to use an LM and a resistor current circut to make the inversion for the compressor. Operational transconductance amplifier ota and buffer. NJR wanted to know my annual usage of the ‘ I predict that if the CA is not discontinued, sales will pick up as the dat 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 cata new applications being developed.

Don Tillman at November 10, Surface mount does not belong on an airplane or in a car! Until then, it won’t appear on the entry. The US is the largest exporter of industrial controls – which use lots of linear ICs. The operational transconductance amplifier ota is an amplifier whose differential input voltage produces an output current. Pond at May 20, 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.


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. Cn ca ca a ca ae ca am ca am96 ca e ca m ca m96 fn intersilcorp ca ae datasheet pdf downlaod from datasheet. Along those lines, the is inspirational for new designs.

Do sheef know if another company like the one that purchased the old fab equipment is considering carrying on producction when the current stock depletes? Wide bandwidth operational transconductance amplifier ota.

Ok, enough ranting and raving. None of the other chips comes close in these areas, so if you can only support one OTA chip, that’s the one.
