S- I will also try conencting the Amplifier in Inverting and Non Inverting mode, to see which results issue forth. Yes, my password is: Datashet 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.

The attachment contains an image of the circuit and waveform for the calculation above. Thus the Slew Rate can be calculated thus: 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.


I gave those values from the lab below. Oct 23, 5. The input signal is a 2V square wave. Oct 24, 7.

No, create an account now. 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.

Operational Amplifier

Your name or email address: 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. 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.

Anyway, thanks for the help thus far- any further thoughts that anyone may have regarding this problem would be greatly appreciated.

Quote of the day. Can an op-amp with high slew rate replace an op-amp with low slew rate in a partic Dattasheet by kling in forum: Observing the Output Square Wave, some Slewing is clearly evident.

I am assuming that this reading can be obtained without placing a particular kind of load at the Op-Amp’s output, as the Datashheet does not specify one.

You will see appoximately 0. Apr 26, 3, 1, Dec 20, 10, 1, Looking forward to hearing some suggestions. Slew rate of op-amp Posted by jegues in forum: The assignment simply states: 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.
