If R3 is too low a value for your transducer, check the amplifier data sheet to see how high a value you can use. Sign up or log in Sign up using Google. The LM series are precision high speed operational am. Also, to datqsheet, do the ground symbols on your diagram correapond to the 0v terminal of the power supply?

These connections are the input and output socket grounds, the feedback network ground R2the power datsaheet decoupling caps C2, C3 grounds, and the wire dafasheet the power supply. As far as DC continuity is concerned, yes. Thanks for your patience. The high speed and fast settling time of these op amps make. 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.
The LM series has internal unity gain frequency compen- sation. As a hint, read through my answer and see whether you can spot any words text that refer to those components. Less critical R3 might as well ground there anyway.
Decouple the output with a few 10s of ohms series resistor R4 so the amplifier isn’t driving the capacitance directly. Im a relative beginner. The hydrophone is attach to a coaxial cable, which is diagrammed as such on catasheet data sheet. When I measure my Vout with an oscilloscope with the power supply turned on, I get a randomly oscillating garbage output, so clearly I am doing something wrong. Post as a guest Name.
Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed.
They feature a factor of ten increase in speed over general purpose devices without sacrificing DC performance. As a minimum, 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 at the gain of two here, all that will be for naught if you’ve built a bird’s nest on a proto-board.
However, unlike most internally compensated amplifiers, external fre- quency compensation may be added for optimum perfor- mance. These devices are easy to apply and offer an order of. They feature a factor of ten increase in. 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. I am trying to work from this very general circuit diagram I have found online and in an electronics textbook I own.

dztasheet What were you referring to by this. It is possible to bootstrap this resistor to reduce the loading if needed. Is this what you’ve got? The LM series has internal unity gain frequency compen.
Email Required, but never shown. This considerably simplifies its application since no external components are necessary for operation. 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.
