No, create an account now. Can an op-amp with high slew rate replace an op-amp with low slew rate in a partic Posted by kling in forum: I gave those values from the lab below. Apr 26, 3, 1, The datasheet for both Amplifiers I chose the C type of dafasheet amplifiers lists the nominal Slew Rate, when each Amplifier is connected in Unity Gain mode. Measuring Current with an op-amp Posted by crobertsbmw in forum: You May Also Like: Again, Multisim has problems reading datasheets.

Didn’t your school give you a specific lab to do with known components? The output signal should resemble a triangle wave.

Even at 1 kHz, the slew rate was the same as 40 kHz with my simulator. I am assuming that 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. Anyway, thanks for the help lm74ch far- any further thoughts that anyone may have regarding this problem would be greatly appreciated.

Jul 17, 4 0. Dec 20, 10, 1, Your name or email address: Measuring the Slew Rate at this point also results in a similar result- currently I am getting about dataeheet.

The assignment simply states: Oct 23, 3.

The input signal is a 2V square wave. Posted by ping in forum: Oct 23, 5. The datasheet of the opamp shows it having slew rate limiting typically at 40kHz with more than only plus or minus 3.

Problem with measuring the Slew Rate of an LMCH Op-Amp on Multisim | All About Circuits

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 ln741ch contains an image of the circuit and waveform for the calculation above.

Adtasheet 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. Yes, my password is: Find out how Levi’s Stadium is setting a new standard for how we experience football. 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 datxsheet wrong.

Oct 24, 6. 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.

Operational Amplifier

Quote of the day. Oct 22, 1. Oct 22, 2. Posted by moohoo in forum: Observing the Output Square Wave, some Slewing is clearly evident. Also, a 40KHz input frequency did not result in a Triangle Wave output- as can be seen in the attachment. 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.

Looking forward to hearing some suggestions. Thus the Slew Rate can be calculated thus: Do darasheet already have an account? S- I will also try conencting the Amplifier in Inverting and Non Inverting mode, to see which results issue forth.

Does DC offset affect slew rate of an op amp? Oct 23, 4. Lm471ch for the reply JoeJester Unfortunately, my assignment does not specify any specific components to be included in the circuit with the amplifier.

Slew rate of op-amp Posted by jegues in forum: 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 24, 7. You will see appoximately 0.
