    What is causing low frequency oscillations in LM324 OP-AMP output?

    Waveform is captured in CRO AC coupling mode...Even in multimeter oscillation was clearly visible as digits kept on changing...

    What is causing low frequency oscillations in LM324 OP-AMP output?

    Capacitor is Not connected(NC)...is that noise? what it should be called? I have attached o/p waveform ...Each division is 50 mV...is that noise? what it should be called?

    What is causing low frequency oscillations in LM324 OP-AMP output?

    Value of components are R119 =R110=99k , R112=R117=499k...gain is 1/5 ...it is atteneuator...and input is 3.2 V DC

    What is causing low frequency oscillations in LM324 OP-AMP output?

    it is just difference amplifier with gain of 1/5

    What is causing low frequency oscillations in LM324 OP-AMP output?

    At output of LM324, 50 mV low frequency (Around 5 to 10 Hz) oscillations were observed when it was used as attenuator for pure DC application...what could be the reason?
