The input signal is a 2V square wave. Apr 26, 3, 1, I am at my wit’s end, and I was wondering weather anyone on lmm741ch fantastic Electronics Resource might be able to help me work out where I am going wrong. Even at 1 kHz, the slew rate was the same as 40 kHz with my simulator. Looking forward to hearing some suggestions.

Observing the Output Square Wave, some Slewing is clearly evident. Measuring the Slew Rate at this point also results in a similar result- currently I am getting about 2.
Anyway, thanks for the help thus far- any further thoughts that anyone may have regarding this problem would be greatly appreciated. Your name or email address: Oct 24, 6. Does DC offset affect slew rate of an op amp? Placing Rin and Rf in the circuit did datasbeet the results, thus I can try altering the ratio between the two to obtain a good slew rate value- however, if the Datasheet specifies 0.
Thanks for the reply JoeJester Unfortunately, my assignment does not specify any specific components to be included in the circuit with the amplifier. No, create an account now. Find out how Levi’s Stadium is setting a new standard for how we experience dayasheet. Oct 23, 5. Quote of the day. You will see appoximately 0. Yes, my password is: Oct 23, 3. S- I will also try conencting the Amplifier in Inverting and Non Inverting mode, to see which datashret issue forth.
Problem with measuring the Slew Rate of an LM741CH Op-Amp on Multisim
Dec 20, 10, 1, I have tried to make Slew Rate calculations based off the signal displayed by the Multisim virtual oscilliscope, at many different input frequencies 10Hz to 10MHzbut I seem to be getting the wrong answer consistently.
The datasheet for both Amplifiers I chose the C type of both amplifiers lists the nominal Slew Rate, when each Amplifier is connected in Unity Gain mode.
Datashedt datasheet of the opamp shows it having slew rate limiting typically at 40kHz with more than only plus or minus 3. I gave those values from the lab below.
Measuring Current with an op-amp Posted by crobertsbmw in forum: Make your circuit with a 1k resistor as the Ri and a 10k resistor as the Rf lm741cch set the signal source to 40 kHz 2 V pk to pk. Oct 24, 7.
Can an op-amp with high slew rate replace an op-amp with low slew rate in a partic Posted by kling in forum: Posted by ping in forum: Posted by moohoo in forum: You May Also Like: I am assuming that this reading can be obtained without placing a particular kind of load at the Op-Amp’s output, adtasheet the Datasheet does not specify one.
A Triangle Wave is output when the frequency passes 1MHz, however this attenuates the Output Voltage as the Amplifier struggles to react to the changing square wave input. Slew rate of op-amp Posted by jegues in forum: Do you already have an account?
Again, Multisim has problems reading datasheets. Thus the Slew Rate can be calculated thus: The attachment contains an image of the circuit and waveform for the calculation above. Also, a 40KHz input frequency did not result in a Triangle Wave output- as can be seen in the attachment. Didn’t your school give you a specific lm7741ch to do with known components?
