Simple question about solenoids These two op-amps are much higher speed op-amps than the and require a lot of Use a rail-to-rail amplifier. Post as a guest Name. Andy aka k ld356 May 19, 1, 1, Simple Question about Current Posted by paul in forum: Now here’s my problem: 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.

I’m curious – what is it about your circuit that makes you think a JFET input stage can’t “handle it”? Simple question about Flow?

Posted by Calcifer in l356 First step is to verify all of the power supply voltages, not just on the power supply board, on all of the boards. Is there any “standard” modern rail to rail opamp with GBP around 5Mhz you could recommend?


Simple question about LF Reply to Thread.

Is this how this old opamp is supposed to operate? What country are you in?

Randomly check that all the voltages are getting to all the boards. I have a circuit in which a square wave with smaller amplitude should be amplified with an opamp. Jul 2, 9.

It won’t at all properly work on a single 3. Posted by J6Str in forum: Yes, a TL would be a reasonable replacement. Assuming it can swing within 2 volts of Vcc, then yes, it should work as simulated. If you don’t need any of the more extreme performance fl356 rail to rail input or output, ultra low noise, ultra wide bandwidth, etc.

Jul 1, 7. So, is this op-amp is to repair your scope? Devices developed in the current century have a boatload of advantages in both performance and ease of use over the first stumbling step devices. Have you checked the necessary supply voltage of the and are you applying it accordingly? Jun 30, 1.

Here is the circuit: No, create an account now. The configuration shown doesn’t give a gain of 4.
