While the data sheet says this amplifier will be datasyeet at unity gain, so more stable at the gain of two here, all that will be for naught if you’ve built a bird’s nest on a proto-board. A few 10s of pF placed across R1 C4 can sometimes restore stability in these cases.

If R3 is too low a value for your transducer, check the amplifier data sheet to see how high a value you can use.

The high speed and fast settling time of these op amps make.

They feature a factor of ten increase in speed over general purpose devices without sacrificing DC performance. Sign up using Facebook. Sign up or log in Sign up using Google. Post as a guest Name. However, I am confused about what input and outputs correspond to what. What were you referring to by this. Further, a single capacitor can be added to reduce the 0.


I tend to pick a single point in the amplifier star ground pointand wire the critical ground connections back to that. The LM series has internal unity gain frequency compen. If you are still having problems, read these parts carefully. Home Questions Tags Users Unanswered. However, it would be unwise to wire it like that.

Overcompensation can be used with.

For inverting applications, feedforward compensa. The LM series are precision high speed operational am. The data sheet does talk about stability modifications you can make with extra capacitors connected to pins not shown on this simple schematic.

A good way to get oscillatory performance out of an otherwise good amplifier is to drive a pure capacitive load with it, like a coaxial cable into an oscilloscope. As of now I am using a connecter to break out the coaxial cable to a “positive”, and “negative” wire.


Thanks for your patience. This considerably simplifies its application since no external components are necessary for operation. These devices are easy to apply and offer an order of.

I am trying to amplify an audio signal generated by a hydrophone. Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed.

Are all datasheeet my input and outputs correct. As a hint, read through my answer and see whether you can spot any words text that refer to those components. Generally when a component in a schematic is labelled ‘see text’, it means you have to refer to the text that talks about the schematic.

Decouple the output with a few 10s of ohms series resistor R4 so the amplifier isn’t driving the capacitance directly.
