The whole build cost about $5.00 and took less than an hour to put together. I built a small, battery-powered amplifier into the case of my guitar using the LM386 and minimal extra parts. Even though my LM386 model is not exactly like the part used in the project, it is still practical for looking at the electrical characteristics of op amps and getting more familiar with LTSpice. I actually got this design to slightly out-perform the part I based my design off of, but it only works from 2 to 6 volts. I designed an op amp based on the LM386, but with MOSFETs instead of BJTs. LM741 OPERATIONAL AMPLIFIER LECTURE NOTES DOWNLOADBelow is a button where you can download the project files for what I am about to show you. ![]() I couldn't find a model I could import into LTSpice and I started from scratch. LM741 OPERATIONAL AMPLIFIER LECTURE NOTES PORTABLEIn this case, the mini portable guitar amp project case, I took it too far. ac analysis the gain is given in terms of decibels. Mouser offers inventory, pricing, & datasheets for lm741 Operational Amplifiers - Op Amps. If both output and input are expressed in terms of voltage then the units will be Volt/Volt. lm741 Operational Amplifiers - Op Amps are available at Mouser Electronics. When were talking about gain, we are taking the ratio of the output to the input. Gain Bandwidth Product is constant and describes the op amp gain behavior with respect to frequency. You can extend the bandwidth (to a certain degree) but at the cost of the gain. What Makes up an Op Amp The 741 Example Output Stages: Class B Output. We need to be aware of the Gain-Bandwidth Product here.
