Slew rate problems
This amplifier exhibited no slew rate induced problems. Conclusion. By now you the reader should understand that slew rate has precious little to do with the dynamics or punchiness of an amplifier, although one can imply that a more powerful amplifier requires a higher slew rate. Slew rate is all about effective bandwidth. Slew rate problems at high frequencies Maximum slope of a sine wave is 2*pi*Vp so that is the figure to use, not peak to peak. Bear in mind the values in the data sheet are "typical" and quoted at a specified load so it would be risky to assume you can run so close to the datasheet value. I would like a reasonable margin between what is Anything related to slew rate (SR in datasheets), i.e. a characteristic parameter of analog amplifier circuits (notably operational amplifiers). The slew rate of an amplifier is the maximum rate of variation that the input signal can exhibit in order for the output amplified signal to follow it without distortion. Slew rate is basically the rate at which the output reflects the change in the input. Coming to your question, you have mentioned that the op amp should be ideal. Thus for an ideal op amp the slew rate should be inflinity.Which means that the outp Figure 16. Inrush Current and Voltage Drop with Slew Rate Control With the controlled slew rate of the TPS22965, the maximum inrush current drops from 6.46 A to 960 mA. The 1.8 V output of the buck converter also shows no significant voltage drop. 5 Conclusion
Operational amplifier slew rate is key for many electronic circuit designs: designing for The slew rate issues arise from the internal circuitry within the op amp.
A typical general purpose device may have a slew rate of 10 V / microsecond. This means that when a large step change is placed on the input, the device would be able to provide an output 10 volt change in one microsecond. The figures for slew rate change are dependent upon the type of operational amplifier being used. The slew rate of an op is the maximum rate of change of output voltage per unit time. It is normally expressed on op amp datasheets as unit volts per microsecond. So it's the amount of voltage an op amp can output each microsecond that passes. So based on this, the slew rate is time dependent. There are several problems that may stem from having "too much" slew rate: Slew rate correlates loosely with op-amp bandwidth, so using an op-amp with a much higher slew rate than is actually required means you're making your circuit sensitive to things it doesn't need to be sensitive to. High slew rate problems with Atlas EQ-G GOTO mount - posted in Mounts: Abstract: Atlas EQ-G works fine but binds when slewing at 800x+ A number of years ago I inherited an Orion Atlas EQ-G GOTO mount and Meade 203/SC EMC telescope from my father-in-law. I was given all his astronomy gear, but the SynScan controller was oddly missing and a replacement was quite expensive, so the mount and scope This amplifier exhibited no slew rate induced problems.

I seem unable to tweak the mount with the hand controller as the slew rate keeps. .. I have the same Problem here. i am at Ubuntu 17.10 and Kstars bleeding
In this video, the slew rate of an Op-Amp has been explained with solved examples. What is Slew Rate: It defines the maximum rate at which the output of the op-amp can change.

This calculator computes the minimum slew rate necessary to output a certain voltage at a certain frequency, calculates the maximum output frequency an op
Operational amplifier slew rate is key for many electronic circuit designs: designing for The slew rate issues arise from the internal circuitry within the op amp. Department of Electrical Engineering. Indian Institute of Technology, Delhi. Lecture-51. Op-Amp Compensation, Slew Rate and some Problems. 27 Aug 2017 This set of Linear Integrated Circuit Multiple Choice Questions & Answers (MCQs ) focuses on “Slew Rate – 1”. 1. Slew rate is defined as the 13 Nov 2014 Slew rate limits will cause distortion at high output frequency and for high bandwidth communications, can cause problems with lower speed 26 Feb 2019 Engineers often confuse rise time and slew rate. They are similar, but we often associate slew rate with amplifiers and analog signals as
Slew rate limiting as i2c is a relatively slow bus, and low slew rates help to avoid EMC and signal integrity issues. Similarly with the glitch filter,
Slew rate is simply the rate-of-change of some parameter, such as speed or voltage, with time. The term "load the slew rate" makes no sense.
