LF/LF/LF/LF/LF/LF/LF JFET Input Operational Amplifiers. General Description. These are the first monolithic JFET input operational. 1 Nov LF (AV=5). • High Impedance Buffers. Extremely fast. 4. μs settling time to %. • Wideband, Low Noise, Low Drift Amplifiers. These are the first monolithic JFET input operational amplifiers to incorporate well matched, high voltage JFETs on the same chip with standard bipolar.

May 19, 1, 1, So, is this op-amp is to repair your scope? 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.

Is this how this old opamp is supposed to operate? Your name or email address: First step is to verify all of the power supply voltages, not just on the power supply board, on all of the boards.

Is this because I’m using a single supply? These two op-amps are much higher speed op-amps than the and require a lot of Yes, my password is: I’m curious – what is it about your circuit that makes you think a JFET input lf3356 can’t “handle it”?

Simple question about capacitor Posted by Bamerni in forum: I am planning to use the LFN for a lf36 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.

It’s been a while since I’ve messed around with this part, so I don’t remember the output voltage range. The configuration shown doesn’t lf3566 a gain of 4.

Guess repairing this scope is impossible.

Apr 24, 7, 1, I have a circuit in which a square wave with smaller amplitude should be amplified with an opamp. The output voltage swing will also clamp at a volt or so above the negative rail 0V in your set up so this will be another problem. Use a rail-to-rail amplifier.
