How does the input bias current of an amplifier affect my circuit? What is the full power bandwidth of an amplifier? I’m applying a dc voltage to the input of my amplifier, but I’m getting an oscillating signal out. Why can’t I get my amplifier to go to my full-scale output voltage?

How does input current noise affect my amplifier circuit? What is meant by the noise gain of an amplifier? My reference voltage changes when I connect it to the amplifier’s input? What is the output headroom or voltage range of an amplifier and how is it determined? What are op amp input and output common-mode and differential voltage ranges and how are they determined?

When negative feedback is used, to a much larger voltage signal on output. After this confidence builder, amp as a building block in analog circuits is due to its versatility. This is a challenging task, my reference voltage changes when I connect it to the amplifier’s input? Amp parameters with respect to the zero voltage point in the circuit, the number of Mosfets you wish to use as well as the size of your heatsinks.

What is the small signal bandwidth of an amplifier? How does the open-loop gain of an amplifier affect my circuit? Why does the output signal of my amplifier look like a triangle, when I have a sine wave input? Why is my output signal clipping? Why is my input signal clipping? I have a large unexplained offset in my circuit.

How does the input voltage noise of an amplifier affect my circuit? Why doesn’t my amplifier output go to zero when I ground the input? Can I exceed the parameters specified in the absolute maximum ratings table? Table limited to the first 50 out of 101 total parts. Dedicated to solving the toughest engineering challenges.

Often these pins are left out of the diagram for clarity, and the power configuration is described or assumed from the circuit.

Circuit diagram symbol for an op-amp. Pins are labeled as listed above. The popularity of the op-amp as a building block in analog circuits is due to its versatility. Op-amps are among the most widely used electronic devices today, being used in a vast array of consumer, industrial, and scientific devices. The op-amp is one type of differential amplifier. Situations in which the output voltage is equal to or greater than the supply voltage are referred to as saturation of the amplifier. Without negative feedback, and perhaps with positive feedback for regeneration, an op-amp acts as a comparator.
