Further, a single capacitor can be added to reduce the 0. As far as DC continuity is concerned, yes. Less critical R3 might as well ground there anyway. Post as a guest Name.

They feature a factor of ten increase in speed over general purpose devices without sacrificing DC performance. The LM series has internal unity gain frequency compen- sation. If you are still having problems, read these parts carefully.

The hydrophone is attach to a coaxial cable, which is diagrammed as such on its data sheet. 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.

I tend to pick a single lm3318n in the amplifier star ground pointand wire the critical ground connections back to that. Home Questions Tags Users Unanswered. Also, to clarify, do the ground symbols on your diagram correapond to the 0v terminal of the power supply? It is possible to bootstrap this resistor to reduce the loading if needed. The LM series are precision high speed operational am. Overcompensation can be used with the amplifier for greater stability when maximum bandwidth lm318b not needed.

They feature a factor of ten increase datashdet. Im a relative beginner. So, currently, my circuit is as such, with ground representing the 0v terminal on the bench top power supply I am using. The LM series has internal unity gain frequency compen.

What were you referring to by this. Further, a single capacitor can be added to. These devices are easy to apply and offer an order of magnitude better AC performance than industry standards such as the LM Sign up using Email and Password.

I am trying to amplify an audio signal generated by a hydrophone. Is this what you’ve got?

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. 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. However, unlike most internally compensated amplifiers, external fre- quency compensation may be added for optimum perfor- mance.
