An OP37 has a 60 MHz GBP, but it is not stable unless you have a gain of 10. Pick one and pull up the data sheet and make sure that it is unity gain stable that has a model in your simulator.įor example an OP27 has an 8 MHz GBP and is unity gain stable. NI Multisim Live lets you create, share, collaborate, and discover circuits and electronics online with SPICE simulation included. Fundamentally you can spend days choosing an op amp. ![]() Open up two windows one the selection in your simulator and the other being a parametric searchįilter the search on single op amps with a GBP between 10 and 50 MHz, active part, single op amp per package. I am not sure what you have models of in your simulation package. If you need the part to work at 100 times the cutoff frequency lower the frequency of your design until the LM741 works then pick with with a GBP that is the ratio of the two frequencies times 1.7 MHz. The vertical axis is the ratio of the output amplitude to the input amplitude in decibels. You have plotted the log-magnitude response in decibels (dB). Shifting it lower tells you what to expect when you get the new part. H() H ( ) or H(j) H ( j ) is the sinusoidal transfer function. Try something that has a gain bandwidth product greater than 10 MHz, that is unity gain stable.
