Op Amp Slew Rate - Details Formula Calculator » Electronics Notes

The slew rate of an op amp or any amplifier circuit is the rate of change in the output voltage caused by a step change on the input. It is measured as a voltage change in a given time - typically V / µs or V / ms. Effect of op amp slew rate. A typical general purpose device may have a slew rate of 10 V / microsecond.

Slew Rate Calculator - Learning about Electronics

So the first calculator calculates the minimum slew rate that is necessary to output a certain voltage at a certain frequency. Say, we want to output 10V at 25MHz. Plugging this into the formula, slew rate=2πfV= 2 (3.14) (25,000,000Hz) (10V)= 1,570,000,000V/s. Converting this to V/μS, we divide this nuer by 1,000,000 to get 1570V/μS, which
