    IC Help

    rybitski, It is true you must understand basic electronic theory to understand how to utilized IC's in circuit, especially if you want to design with them.  But even then you will not totally understand how or what is going on inside them fully.  So I found it helpful to view them as black...

    Op amp theory Q's

    Hi all, Ok I have another question regarding op amp theory.  What is the best way to make a op amp buffer?  Most times you see two 10K resistors for this with a non-inverting input, but would not just a short between the output and the negative input work the same?  What is the difference? Now...

    Op amp theory Q's

    I found one thanks, I have been reading, this is what I needed, but to be quite honest you do need a little bit of background to grasp all of it.  It would be nice to for things to be written in a bit more common language, I miss some of the detail stuff. TG :)

    Op amp theory Q's

    With regard to R3, R4, R11, and R12. The value you want depends on the other values you are using in the loop.

    Op amp theory Q's

    I thought this quote from a converstation I had with another designer might help others understand the reason  for pursuing a design with resistors that bleed open loop gain in an op amp circuit.  The idea is to allow the op amp to function in an area that it operates in a more stable...

    I2C interface and user controls.

    I really like the idea of I2C contol of audio and home theater components.  A lot of IC's use the Philips I2C standard to control  a IC volume control, input selection, bass/treble controls, and anything else that we use to control with pots and switches on from pannels.  Does anyone know of a...

    Op amp theory Q's

    Well I haven't gotten the "noise-gain" resistor design implimented to "hear" it yet.

    Op amp theory Q's

    The reason for the two op amps is that the second corrects the phase back to where it was in the begining.

    Op amp theory Q's

    Audioguru, R3, R4, R9, R10, were inserted in this design based on the design notes below, see the subtitle "noise gain manipulation".

    Ok I am going to try to post the schematic in this post. TG :)

    Op amp theory Q's

    Audioguru, While I figure out how to post a schematic perhaps you could answer a few more questions.  Are these supply caps your talking about in series with the supply, or between the positive and ground of the supply?  What starts to happen the further from the supply pins of the op amp you...

    Op amp theory Q's

    Audioguru, Currently the circuit I am tweaking and experimenting with is a two stage inverting opamp configuration.  I really like the idea of stages and components not effecting each other, so i try to issolate and buffer them as much as possible.  For instance on my first opamp stage I use...

    Op amp theory Q's

    I had higher hopes for this thread, not that some of you haven't delivered, but I was hoping this would go in the direction of some experiences some of you had in developing circuits with opamps.

    Op amp theory Q's

    Indulis, I wish you could come over and I could have you listen to this little preamp that I made for the purpose of checking out opamps.  I don't know why but the AD843 sounds much cleaner than say a TL072.  I don't know enough about these specification to understand what is over kill, this is...

    Op amp theory Q's

    Well for the last several months I have been reading everything on the net, and in some books about opamps.
