For operation with 10-V output pulses with the requirement that the sum of the rise and fall times represent only 20% of the pulse width (at half amplitude), what is the slew-rate requirement for an op amp to handle pulses 2 µs wide? (Note: The rise and fall times of a pulse signal are usually measured between the 10%- and 90%-height points.)

Operational Amplifiers topics include: Ideal operational amplifiers, inverting and non-inverting configuration, differentiators and differential amplifiers, operational amplifiers, finite open loop gain effect, circuit performance bandwidth and large signal operations. An operational amplifier (op-amp) is a high-gain electronic voltage amplifier that has a differential input and a single-ended output. It produces an output voltage by applying an open-loop gain to the difference between the voltage at the noninverting input terminal and the voltage at the inverting input terminal.  Op-amps...

An operational amplifier (op-amp) is a high-gain electronic voltage amplifier that has a differential input and a single-ended output. It produces an output voltage by applying an open-loop gain to the difference between the voltage at the noninverting input terminal and the voltage at the inverting input terminal. 

Op-amps are also known as instrumentation amplifiers. They are versatile and have many uses, including as a PID/PI controller in instrumentation. They are also used in high-quality imaging applications because of their high gain. 

An ideal op-amp has the following characteristics:
No distortion
No meaningful power
Infinite amplification
No noise
Infinite input resistance
Infinite frequency response
Accepts signals of any voltage
Infinite gain
Zero output impedance 

Practical op-amps draw a small current from each of their inputs due to bias requirements or leakage. 

Here are some other types of op-amps:
Inverting amplifier: The output voltage is expressed as a function of the input current.
Summing amplifier: An op-amp configured in a specific manner.
