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. No, create an account now. Oct 22, 2. Slew rate of op-amp Posted by jegues in forum: Quote of lm41ch day.

Operational Amplifier

Oct 23, 4. Does DC offset affect slew rate of an op amp? The output signal should resemble a triangle wave. 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. Oct 23, 5. Even at 1 kHz, the slew rate was the same as 40 kHz with my simulator.

Again, Multisim dataeheet problems reading datasheets. I am assuming datashet this reading can be obtained without placing a particular kind of load at the Op-Amp’s output, as the Datasheet does not specify one. 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. The datasheet of the opamp shows it having slew rate limiting typically at 40kHz with more than only plus or minus 3.

Your name or email address: Anyway, thanks for the help thus far- any further thoughts that anyone may have regarding this problem would be greatly appreciated. Yes, my password is: Measuring the Slew Rate at this point also results in a similar result- currently I lm41ch getting about 2.

Also, a 40KHz input frequency did not result in a Triangle Wave output- as can be seen in the attachment. Thanks for the reply JoeJester Unfortunately, my assignment does not specify any specific components to be included in the circuit with the amplifier.

Measuring Current with an op-amp Posted by crobertsbmw in forum: Jul 17, 4 0.


Looking forward to hearing some suggestions. Oct 22, 1.

Thus the Slew Rate can be calculated thus: You May Also Like: The attachment contains an image of the circuit and waveform for the calculation above. Placing Rin and Rf in the circuit did improve 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.

Can an op-amp with high slew rate replace an op-amp with low slew rate in a partic Posted by kling in forum: The input signal is a 2V square wave.

Observing the Output Square Wave, some Slewing is clearly evident. I gave those values from the lab below.

S- I will also try conencting the Amplifier in Inverting and Non Inverting datashheet, to see which results issue forth. Oct 23, 3. Oct 24, 7. Didn’t your school give you a specific lab to do with known components?
