    Circuit - oscilloscoop result

    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...

    Circuit - oscilloscoop result

    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

    Circuit - oscilloscoop result

    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"

    Circuit - oscilloscoop result

    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)

    Circuit - oscilloscoop result

    Well This is the circuit

    Circuit - oscilloscoop result

    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...

    Tina TI models for LT1054

    Sorry but i don't find the ltspice simulator that impressive And certainly don't like the editing features

    Tina TI models for LT1054

    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???

    Tina TI models for LT1054

    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? https://www.ti.com/lit/ds/symlink/lt1054.pdf Please...

    ItsyBitsy M0 Express & AD5254 Digital POT

    Hi, I just want to set all pots to a certain value. Starting with pot 1 I know there are examples in the datasheet But i don't seem to get them work

    ItsyBitsy M0 Express & AD5254 Digital POT

    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 https://www.analog.com/media/en/technical-documentation/data-sheets/AD5253_5254.pdf I based...

    [SOLVED] making -15/+15v out of single power supply 12Vdc Problem

    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?

    [SOLVED] making -15/+15v out of single power supply 12Vdc Problem

    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...

    [SOLVED] making -15/+15v out of single power supply 12Vdc Problem

    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...
