I’m curious – what is it about your circuit that makes you think a JFET input stage can’t “handle it”? Andy aka k 10 Do you already have an account? Hi, I agree that the more recent op amps work better than the old ones.

Jul 1, 4. I am planning to use the LFN for a gain multiplier and sign inverter applicationbut i don’t know if the opamp can handle it like thebecause this one is a J-fet based opampand i am afraid it shouldn’t be used as a normal one. Is this because I’m using a single of356

However, I noticed that it doesn’t seem to work below 5V at all it pulls up the positive input to some DC voltage, overlaying the signal if I don’t use a decoupling cap. Of course the max output voltage could be limited as lf36. This technical brief explains two distinct types of electromagnetic interference.

First step is to verify all of the power supply voltages, not just on the power supply board, on all of the boards. Jul 4, l3f56 Home Questions Tags Users Unanswered.

Yes, a TL would be a reasonable replacement. So after making the circuitall lf3556 opamps on the scope PCB were working fine.
