Slew rate of op-amp Posted by jegues in forum: Do you already have an account?

LMCH Datasheet pdf – Operational Amplifier – National Semiconductor

Quote of the day. Posted by ping in forum: Thanks for the reply JoeJester Unfortunately, my assignment does not specify any specific components to be included in the circuit with the amplifier. Oct 23, 4. Your name or email address: 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 24, 6.

Posted by moohoo in forum: 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. Thus the Slew Rate can be calculated thus: Does DC offset affect slew rate of an op amp? Even at 1 kHz, the slew rate was the same as 40 kHz with my simulator. You will see appoximately 0. Again, Multisim has problems reading datasheets.

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. The assignment simply states: The output signal should resemble a triangle wave. Oct 22, 1. 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.

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

The input signal is a 2V square wave. Looking forward to hearing some suggestions. 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.

No, create an account now. Oct 22, 2. The attachment contains an image of the circuit and waveform for the calculation above. Measuring Current with an op-amp Posted by crobertsbmw in forum: The datasheet for both Amplifiers I chose the C type of both amplifiers lists dataaheet nominal Slew Rate, when each Amplifier is connected in Unity Gain mode.

Operational Amplifier

The datasheet of the opamp shows it having slew rate limiting typically at 40kHz with more than only plus or minus 3. Measuring the Slew Rate at this point also results in a similar result- currently I am getting about 2. Dec 20, 10, 1, Yes, my password is: Oct 23, 3. I gave those values from the lab below. dattasheet


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

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 datxsheet 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 dataheet focus on for the purposes of this question. 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.

Also, a 40KHz input frequency did not result in a Triangle Wave output- as can be seen in the attachment.

Oct 23, 5. Observing the Output Square Wave, some Slewing is clearly evident.
