Does DC offset affect slew rate of an op amp? The datasheet of the opamp shows it having slew rate limiting typically at 40kHz with more than only plus or minus 3. Oct 23, 4. S- I will also try conencting the Amplifier in Inverting and Non Inverting mode, to see which results issue forth.

Oct 24, ddatasheet. The assignment simply states: Oct 22, 1. Oct 23, 5.

Problem with measuring the Slew Rate of an LM741CH Op-Amp on Multisim

Thus the Slew Rate can be calculated thus: Do you already have an account? You will see appoximately 0. I am at my wit’s end, and I was wondering weather anyone on this fantastic Electronics Resource might be able to help me work out where I am going wrong. Looking forward to hearing some suggestions.

Placing Rin and Rf in the circuit did improve the results, thus I can try altering the ratio lm74c1h the datashwet 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. I am assuming that this reading can be obtained without placing a particular kind of load at the Lm714ch output, as the Datasheet does not specify one.


Quote of the day. Again, Multisim has problems reading datasheets. Yes, my password is: Posted by moohoo in forum: Can an op-amp with high slew rate replace an op-amp with low slew rate in a partic Posted by kling in forum: Oct 23, 3.

Find out how Levi’s Stadium is setting a new standard for how we experience football. This is being facilitated through the use of Multism v11, in which I have constructed a Unity Gain circuit with an LMCH, which is the Op-Amp that I wish to focus on for the purposes of this question.

The attachment contains an image of the circuit and waveform for the calculation above.

The output pm741ch should resemble a triangle wave. Didn’t your school give you a specific lab to do with known components? You May Also Like: 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.

Observing the Output Square Wave, some Slewing is clearly evident.

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. Oct 22, 2. Even at 1 kHz, the slew rate was the same as 40 kHz with my simulator.


Slew rate of op-amp Posted by jegues in forum: I lk741ch those values from the lab below. Your name or email address: Apr 26, 3, 1, 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. No, create an account now. Measuring Current with an op-amp Posted by crobertsbmw in forum: Anyway, thanks for the help thus far- any further thoughts that anyone may have regarding this problem would be greatly appreciated.

Measuring the Slew Rate at this point also results in a similar result- currently Lm7741ch am getting about 2. Make your circuit with a 1k resistor as the Ri and a 10k resistor as the Rf and set the signal source to 40 kHz 2 V pk to pk.

Posted by ping in forum: Jul 17, 4 0. Also, a 40KHz input frequency did not result in a Triangle Wave output- as can be seen in the attachment. The input signal is a 2V square wave.
