Ok next 'problem'.
I now have a clean signal when nothing is connected to the output.
I just added 4.7uF decoupling caps on +/- 2.5V VCC
But from thee moment i connect the output to the next stage (input of an audio interface/mixer) (rme fireface)
There is noise again (less then beforee) on...
Dont think defective channel on the scoop (i interchanged them, same result)
defective op-amp? maybe
But i rather go for the solderless breadboard in first place, try to solve that and then i'll see from there
It's indeed a soldeerless breadboard, i wouldn't really say the wires ar all over the place.
But there are wires indeed. but if that's the problem then i would be solved making a pcb?
I hope so in fact, because then i can more or less neglect the "prob"
Yes but how do one solve this, how to check wiring, groud loop, something else? :-)
Because it's al soldered down well and i cant find any misconnections (it's a simple circuit so not so much to check)
Hi,
I have made an audio analog 'simple' circuit, it has onee audio input and one audio output (via opamp)
The gain is 1
When i probe the incoming and outgoing signals with oscilloscope i see a much fatter noisier line in the out than in the in.
What could be the cause of that? And is it a...
So in fact there is no solution? :-(
I don't get it why producents of components dont publish spice models on there product page.
Or at least source of the compiled models.
They don't want you to sell their products???
Goodmorning all
Anyone can lead me to a 'spice' model that i can import in Tina ti for this Voltage Converter?
It should be a .cir file i guess, but i cant find it.
Or how can you simulate a circuit that uses this component in Tina TI?

I don't know for sure this is the right place to ask this question :-)
I not, lead me into the right direction
I try to make digital pot work with Itsybitsy.
This is the datasheet of the AD5254

Hi,
Can you please explain to me how the +48 volt schematic is possible then ??
Maybe you have to send an e-mail to presonus that they take a laugh at the laws of physics?
Well i am not a professional :-) But i find it logic that i want to be sure that i can make somehow a double power supply (+v/-v) before i start thinking about making a circuit wich could need a double power supply :-)
Otherwise i simply have nothing to test it with, i do not have a variable...
Maybe i have to tell how i came to the idea of making this circuit.
I have a presonus audio pre-amp and i compared my pre-amp circuit with it (soundwise)
I noticed on high volume dc ripple in the ac signal (sound) in my circuit but not at all in the presonus pre amp at same volume level.
I...
