Hey, anyone hear any good songs lately?



I might have, if IC's hadn't killed all of them.

Wait wait wait wait....


I know about "Mr. Yuk":

But what are these "ICs" (pronounced "Ick")?

Are these "ICs" = Home Taping?

or are these so called "ICs"  = Illegal downloading?

Are there "ICs" in communism, too?

Here's what Dan Lavry posted on his own web site 3 years ago:

"The Opamp approach has some advantages over discrete. The component matching capability is great, and one can match more then 2 devices, you can match dozens. Also, the ability to have everything packaged in a tiny area makes all the devices operate at the same temperature which further help greatly.

But Opams have their limitations as well, compared to discrete circuits. First, there are no inductors. Second, the capacitors used in the silicone are limited to very small values (the area is tiny). The caps are also limited in the type of material (fro example, no film type caps and so on…) Last but not least, most opamps are designed for relatively low current, thus limiting the applications when very high current is required. The same is true for voltage. Let me note that some companies specialize in manufacturing high voltage and current devices…

Some of the shortcomings of the opamps are overcome by using them with external parts. Often there are compensation pins on an opamp, enabling the designer to “continue” and “complete” the circuit inside the silicon with external parts. Often a designer can extend the usability of an opamp by use of external parts to cover high voltage, current and power applications, improve the input circuitry and so on…

But at the end of the day, the opamp is a repackaging job, and any comments against an opamp should be viewed as such. I am not for or against opamps. It is just one more part type, and one can and should use it were it makes sense. And one should not use it where it does not make sense. I would not “judge” the quality of a piece of gear based on use (or lack of use) of amps."

an opamp is not a repackaging job..

it is a miniaturization...job... with all the shortcomings you would expect from it.

as Dan Lavry mentioned, they are easy to use also because they do not need expensive selection.

...and some ancillary benefits to the diminutive size, as well!  Don't just throw a baby out with the bathwater. Smaller is better because it is more portable and takes up less space. As mentioned in the quote, the very nature of the silicon chip enables a high level of uniformity to its electrical and thermal properties.  The drawsback to ICs, which he does cite, can be worked around, and this extra effort (say, adding larger parts to the build-out pins) is worth while because of the low cost and various conveniences (thermal, spatial, and precise) of using little ICs for the sections that benefit from them (or are immune to their erstwhile drawsback).

I think thermal distortion is something you want to look at.

that and the fact that IC's cannot use selected components like discrete circuits can, therefore they are designed with a lot more error-correcting circuitry than you'd need with a properly-designed purpose-built discrete circuit.

The Jensen 990 looks pretty discrete to me.

See what you think, I have attached a schematic.

Justin

edit: The schematic is shown for informative reasons, I'm not trying to patronise anyone saying it's "discrete" Smile


Front end = LM394CH super matched transistor pair, in other words, an IC. It also sounds like crap, a MAT 02 or the that part is superior, pop one in your SSL 4k mix amp and report back.

It's not the arrow, it's the indian.

You really need to talk to a chip designer. You are full of missinformation. New devices from Analog Devices are based on thermal and layout matching on a precision level not attainable with discrete components.

Can you show me a discrete opamp that does 1.6 ghz?

Can you show me a discrete that does -154 dbu THD?

Can you show me a discrete opamp that does .8 nv/hz/sq noise?
