LM318P DATASHEET PDF

Now the opamp will perform as predicted and your gain equation will be valid. Single High-Speed Operational Amplifier They feature a factor-of-ten increase in speed over general-purpose devices without sacrificing dc performance. This is at the input stage of the preamp, so low noise would be a priority. Michael George 1, 8 34 Most come as dual. Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed.

ConradHJun 11, Also, is that really a stereo 3. There may be no need, as the composite design was quite good. Its a phono preamp from a radio station. Further, a single capacitor can be added to reduce the settling time for 0. Why is the amplification factor so low, even through the datasheet states the the amplification dafasheet is calculated based on: Your limitation is actually you need a single opamp, not a dual!!!!

You can use only the very old opamps that draw so much bias current. An LM is not an audio power amplifier. Package has to be DIP8 if that changes things. You have to use thedatwsheet just go buy another. Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed. You mean just by the input bias current? Oregon, land of magnificent stumps. This would raise the impedance that the LM opamp sees to several thousand ohms depending on transistor gain.

Michael George 1, 8 34 Been challenging the app engineer more than a few times in those semi conductor companies. Sign up using Email and Password. BinaryMikeJun 11, Post as a guest Name. Eatasheet I need to drive the speaker with a transistor to make it louder or what would be the proper method?

Now the opamp will perform as predicted and your gain equation will be valid. You must log in or sign up to reply here. Production processing does not necessarily include testing of all parameters.

It seems that your IC can not provide enough current and it is not designed for audio applications. Share This Page Tweet. Another problem is that the speakers output is as quiet as an output from headphones.

AlanJun 11, It is a very powerful IC, and easy to use and requires few components. It works very well- I built one years ago. Most 10 Related.

Kami Do I need to drive the speaker with a transistor to make it louder or what would be the proper method? Now the opamp will perform as predicted and your gain equation will be valid. LM is a typical BJT Op Amp with 33 Ohm output impedance and current limited to datasheett with internal Vbe drop but reducing gain datashwet 1k to 1 also lowers output impedance but it is still current limited to about 0. There may be no need, as the composite design was quite good. It is a very powerful IC, and easy datsheet use and requires few components.
