At output of LM124 very low frequency oscillations were observed (around 5 Hz to 10 Hz) when it is used as attenuator for pure Dc application...what could be the reason?
Kamlesh,
You have posted your question to a forum that does not normally handle op amp question. I suggest that you resubmit your question in the "Amplifiers" forum in the sub-group "precision amplifiers."
To provide a meaningful answer we would need more information... circuit diagram and information regarding the nature of the oscillations-- amplitude, etc. A scope photo would be helpful.
Regards, Bruce.
