Slew lm71ch of op-amp Posted by jegues in forum: Quote of the day. S- I will also try conencting the Amplifier in Inverting and Non Inverting mode, to see which results issue forth.

Didn’t your school give you a specific lab to do with known components? Find out how Levi’s Stadium is setting a new standard for how we experience football. Oct 24, 7. 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.

LMCH datasheet, Pinout ,application circuits Operational Amplifier

Yes, my password is: Placing Rin and Rf in the circuit did improve the results, thus I can try altering the ratio between datasueet two to obtain a good slew rate value- however, if the Datasheet specifies 0. Do you already have an account? 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.


The attachment contains an image of the circuit and waveform for the calculation above. Measuring the Slew Rate at this point also results in a similar result- currently I am getting about 2. Oct 23, 5.

Your name or email address: Thus the Slew Rate can be calculated thus: The input signal is a 2V square wave. Datxsheet 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. Apr 26, 3, 1, Does DC offset affect slew rate of an op amp?

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 Datashewt that I wish to focus on for the purposes of this question.

No, create an account now. The assignment simply states: Oct 23, 4. Thanks for the reply JoeJester Unfortunately, my assignment datasheett not specify any specific components to be included in the circuit with the amplifier. Posted by ping in forum: Anyway, thanks for the help thus far- any further thoughts that anyone may have regarding this problem would be greatly appreciated.

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

Also, a 40KHz input frequency did not result in a Triangle Wave output- as can be seen in the attachment. Jul 17, 4 0. Looking forward to hearing some suggestions.

Oct 22, 1. Dec 20, 10, 1, Again, Multisim has problems reading l741ch. 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. Measuring Current with an op-amp Posted by crobertsbmw in forum: Oct 22, 2. 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.


Oct 24, 6. Posted by moohoo in forum: I have tried to lj741ch 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. You May Also Like: You will see appoximately 0. The output signal should resemble a triangle wave. Observing the Output Square Wave, some Slewing is clearly evident.

The datasheet of the opamp shows it having slew rate limiting typically at 40kHz with more than only plus or minus 3.

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.

Even at 1 kHz, the slew rate was the same as 40 kHz with my simulator. Oct 23, 3.
