can someone please explain bandwidth ?

[donald stringer]

I am going to start designing [attempt] an original design, or as much as possible based specifically around the 5532. I am not an an electronic tech and I am operating on basic hobbyist knowledge. But what attracted me to this op-amp is its use in audio circuits. I read that it has a bandwidth of 10mh ?. If someone could explain what this means, in reference to stompbox enthusiast I would really appreciate them sharing their knowledge. :idea:

I think its somehow related to slew rate, and determines the max frequency??

just a guess :-D

[R.G.]

Bandwidth is literally how wide a frequency band the device will pass. Unfortunately, the term is almost meaningless without detailed qualifiers.

In this case, what is meant is that the small signal (less than some arbitrary signal size, but small compared to the power supply) response can be as much as 10 megahertz.

That doesn't help you much. Audio is a frequency range of about 20 Hz to 20kHz. The fact that the 5532 can get to 10mHz doesn't have much to say about the audio response except tangentially.

The now-obsolete 741 opamp had a response of 1Mhz. What that meant was that it had gain of one or greater out to 1Mhz. An opamp with an open loop gain of one is fairly useless, but 1MHz looks good on spec sheets.

What is really good about the 5532 is that it has a wide enough  bandwidth to still have some gain to "waste" on feedback up at the upper end of the audio bandwidth.

I suppose that the bottom line is that the 5532 has enough margin to still look like a good opamp at the high end of the audio range.

Try this, sort of an explanation of how it relates in the digital & analog realms:

Thanks for the responce R.G. and RDV as usual very helpful information. The thought I had running throuhg my head is this. I want to use the 5532 but instead of the usual clipping devices, I wanted to take the output from the 5532 and use inverters from a 4049 to create the clip. But in a step up fashion.[ adding inverter stage or subtracting with a momentary switch or spdt]. secondly I may use an 2n7000 as an input pre-amp stage,[maybe use the mossboost since It is a proven design,and I like the way it overdrives  stompboxes after it. So for a few begging design goals;#1 op-amp of choice has got to be a 5532 #2 cd4xxx chip as signal destroyer #3 I have investigated the 4066 and by studying the tone gods diagram and R.G. post on this subject,as a result have successfully built a dual loop ab box, and have in corporated the same technology on the double d  dual pre-amp from runoff groove instead of 3pdt or dpdt stomp switch. No noise, way cool, whisper quiet electronic switching. That was worth the learning curve I needed to absorb.This project will be built, but it is not like its something that I am planning on selling or anything so if anyone has any constructive ideas I am willing to listen..........

Use your mind or loose it......or my old fathers version was use your head for something besides a hatrack.

This is a cool idea, but you'll really only need one "side" of the 5532 to boost your signal.  Gain of about 10 works well.  Also, the mosfet boost idea is a good one, but it might be better as an alternative to the 5532 rather than an addition to it.
There's probably some good stuff in the archives about signal destruction with the 4049.  Search for 4049 or tube-sound fuzz.  For serious overload, try 2 stages, first with something like 10k input resistor, 100k+100pF feedback, second with 100K + 100pF feedback.

have fun
