how come you guys are:mad:. i am trying to design a circuit
We're not mad. We simply can't help you, because you won't specify what your input(s) are, and what you expect (or want) to see on the outputs.

using resistors capacitors and op amps with high voltage.
Define what is "high voltage" to you.

is 44 v the highest voltage possible with op amps?:confused:
If you would properly explain what your input signal(s) might be, we may be able to offer suggestions as to how to connect it up.

output is unknown.
Well, can you make an attempt at telling us what you want to see? Input voltage or current scaled up or down, or maybe inverted? We don't know.
input is resistors and capacitors with high voltage op amps.
Input and feedback are normally resistive, at least in part. Draw a schematic.

any advice is always welcome.
You really have to give us more to go on.

We don't know what your input(s) are.

We don't know what you need for an output or outputs.

We don't know why you keep asking for higher voltage, single-supply components, and then won't even attempt to tell us what you're trying to do.

Until you explain what you are trying to do, we really cannot help you.

He seems to think that if we would just give him a magic op amp part number, his circuit would work. The fact is that for most applications, there are many different op amps that will do the job. I'll add my voice to the growing throng: We need to see a schematic, or at least a succinct definition of the problem.

i read in the thread apex technologies has high voltage op amps.

up to 350 V any other suggestions welcome.

this is for high industrial application design. :confused:

is jameco a good source for design engineers?

will provide design when initial draft is ready. still searching

for good components.:cool:

It's not Apex Technologies (there are thousands of companies by that name)
It's Apex Precision Power, a division of Cirrus Logic.

Their homepage is here:
http://apex.cirrus.com/en/products/apex/index.html

But since you still haven't given us a clue
what it is you're really trying to do,
there isn't much of a way that we could possibly help you.

You posted some meaningless stuff in the beginning that didn't shed one bit of light on your requirements.

Is it that you simply don't know what your input(s) are, or what you might need for an output?

Or are you afraid to tell us for some obscure reason?

not sure what i need for input or output. new to electronics.

:confused: hope that helps.

You are not so easily confused as I am, Ron.:(
Sorry if I misunderstood you. The OP's sentence had two possible interpretations. My assumption was that no one would seriously think one could actually buy engineers from anywhere (wouldn't that be slavery?), so my conclusion was that you were being sarcastic (not that I would blame you ;)).

:cool:thanks foreveryone's help, the project is nowcomplete.

this thread can be closed unless someone has anything to add.

For this application i need help with 3 Bit flash ADC

along with LM324 Capacitor standard, Resistor is 1K ohms

output is a square or triangular wawe.

hope this clarifies my previous 30 or so posts.:)

It's as clear as mud.:confused:
What does this mean:
LM324 Capacitor standard, Resistor is 1K ohms

output is a square or triangular wawe.

i think sawtooth wawe is also possible.:cool:
Rajit, I have no idea what a sawtooth, triangular, or square wave has to do with a flash A/D. I think we have a big communications problem. Perhaps you can find one of your countrymen who speaks better English than you do, tell him (or her) what you want to say, and have him translate it into English for you. Post the translation here. Don't describe what you are trying to do in little bits and pieces. Do the entire thing in one post.

i am good at english new to electronics thats all.

the sawtooth triangular and square are all output waweforms

hope that helps.:cool:

An A/D has an analog input, and multiple digital outputs. It does not have sawtooth or triangular wave outputs.

I think what he's trying to say is that he wants to build a function generator using an LM324 that will output square, sine, and triangle or sawtooth waves.
