Operational Amplifier

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

The assignment simply states: Oct 22, 2. 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.

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

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 22, 1.


Looking forward to hearing some suggestions. Oct 23, 3. Measuring the Slew Rate at this point also results in a similar result- currently I am getting datashfet 2. Apr 26, 3, 1, Also, a 40KHz input frequency did not result in a Triangle Wave output- as can be seen in the attachment.

A Triangle Wave is output when the frequency passes 1MHz, however this attenuates the Datasheeet Voltage as the Amplifier struggles to react to the changing square wave input.

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. Jul 17, 4 0. Do you already have an account?

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

Dec 20, 10, 1, 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. Didn’t your school give you a specific lab to do with known components? No, create an account now. Again, Multisim has problems reading datasheets. Yes, my password is: Find out how Levi’s Stadium is setting a new standard for how we experience football. 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.

The input signal is a 2V square wave. I am at my wit’s end, and I was wondering weather anyone on adtasheet fantastic Electronics Resource might be able to help me work out where I am going wrong.
