LF356 JFET Op Amp IC

Jul 3, Jul 1, 8. So after making the circuitall the opamps on the scope PCB were working fine. Do you already have an account?

If you don’t need any of the more extreme performance parameters rail to rail input or output, ultra low noise, ultra wide bandwidth, etc. The FET op amps often have a very narrow input range which is not good enough unless the supply voltages are the full plus and minus 15, but you seem to have plus and minus 12 which isnt too bad as long as the input does not get closer than about 4v to either rail.

Yes, my password is: These two op-amps are much higher speed op-amps than the and require a lot of I suggest that you consider the LF Post as a guest Name.

Hi, I agree that the more recent op amps work better than the old ones. Andy aka k 10 Apr 24, 7, 1, It is a much more forgiving and well behaved op-amp. Here is the circuit: BrianDrummond – good spot!

Is there any “standard” modern rail to rail opamp with GBP around 5Mhz you could recommend? Use a rail-to-rail amplifier.

Of course the max output voltage could lr356 limited as well. 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. No, create an account now. They are in stock at Digi-Key and there are Ebay sellers all over the world. I have a circuit in which a square wave with smaller amplitude should be amplified with an opamp.

Randomly check that all the voltages are getting to all the boards. Jul 4,
