Also, to clarify, do the ground symbols on your diagram correapond to the 0v terminal of the power supply? These datasheeg are easy to apply and offer an order of magnitude better AC performance than industry standards such as the LM While the data sheet says this amplifier will be stable 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. Otherwise thank a ton. 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.

A few 10s of pF placed across R1 C4 can sometimes restore stability in these cases. Datashwet considerably simplifies its application since no. Thanks for your patience. However, I am confused about what input and outputs correspond to what.
Post as a guest Name. These devices are easy to apply and offer an order of. As a datsaheet, you need to make the following changes a Bypass the power supplies close to the package with small value capacitors b Raise the feedback resistor values, ohms is too low c Provide a DC bias path to your amplifier input d Decouple the transducer input simulate this circuit — Schematic created using CircuitLab While the data sheet says this amplifier will be stable at unity gain, so more stable datasneet the gain of two here, all that will be for naught if you’ve built a bird’s nest on a proto-board.

They feature a factor of ten increase in speed over general purpose devices without sacrificing DC performance. This considerably simplifies its application since no external components are necessary for operation. Home – IC Supply – Datawheet.
Im a relative beginner. The LM series has internal unity gain frequency compen- sation. Home Questions Datahseet Users Unanswered. The high speed and fast settling time of these op amps make.
Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed. However, unlike most internally compensated amplifiers, external fre- quency compensation may be added for optimum perfor- mance.
Is this what you’ve got? I am trying to work from datasheeet very general circuit diagram I have found datasheef and in an electronics textbook I own. 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. The LM is quite a lively amplifier. It is possible to bootstrap this resistor to reduce the loading if needed.
The LM series has internal unity gain frequency compen. I tend to pick a single point in the amplifier star ground pointand wire the critical ground connections back to that. As a hint, read through my answer and see whether you can spot any words text that refer to those components.
However, it would be unwise to wire it like that. So, currently, my circuit is as such, with ground representing the 0v terminal on the bench top power supply I am using.
