What is gain bandwidth product of 741?
For the 741 op-amp, fc is given as 1 MHz, and the open-loop gain at this frequency is simply one. Gf is defined as the gain- bandwidth product, and for all frequencies this product must be a constant equal to fc. It is generally given in V/μs, and for the 741 op-amp is something close to 1v/μs.
What is gain bandwidth product of an amplifier?
The gain bandwidth product, GBW, is defined as the product of the open loop voltage gain and the frequency at which it is measured. The GBW is constant for voltage feedback amplifiers. It does not have much meaning for current feedback amplifiers, because there is no linear relationship between gain and bandwidth.
What is TL082?
The TL082, TL082A and TL082B are high speed JFET input dual operational amplifiers incorporating well-matched, high voltage JFET and bipolar transistors in a monolithic integrated circuit. The devices feature high slew rates, low input bias and offset current, and low offset voltage temperature coefficient.
What is gain bandwidth product used for?
This quantity is commonly specified for operational amplifiers, and allows circuit designers to determine the maximum gain that can be extracted from the device for a given frequency (or bandwidth) and vice versa.
Why gain bandwidth product is constant?
The gain-bandwidth product (GBW) is calculated by multiplying the absolute value of the gain with ω. which shows that the gain-bandwidth product is a constant, because it is a product between two constants: the op amp open-loop gain and the corner frequency.
How is gain bandwidth calculated?
Open-loop Frequency Response Curve For example, from the graph above the gain of the amplifier at 100kHz is given as 20dB or 10, then the gain bandwidth product is calculated as: GBP = A x BW = 10 x 100,000Hz = 1,000,000.

What is the relation between bandwidth and gain?
Gain and bandwidth in an amplifier are inversely proportional to each other and their relationship is summarized as the unity-gain bandwidth. Unity-gain bandwidth defines the frequency at which the gain of an amplifier is equal to 1.
