Where is the ground on an operational amplifier?
An opamp has a ground terminal on one of the pins.
What is feedback resistance and what is it's use?
Feedback resistance is used to feed back the current obtained at output back into the circuit. Thus a virtual ground concept is developed.this is majorly used in applications of OPAMP[IC 741].
Why voltage gain is high in op amp?
A practical opamp is designed to approach the characteristics of the ideal opamp as closely as possible. The open loop voltage gain of an ideal opamp is infinite, so while this is actually impossible to achieve practical opamps are built with as high an open loop voltage gain as possible.
Similarity between opamp and comparator?
A comparator is simply an opamp with a certain configuation of external circuitry ( a few components) that make it function as a comparator.
What does 10 megohm input impedance mean?
10 megohms is the resistance through which 10 volts would push 10 microamps of current. Input impedance is the resistance seen by a signal source when connected to the input Often, this means there is a 10 megohm resistor in series with the input going to a virtual ground on an opamp circuit. 10 megohms is a common input impedance for a digital voltmeter.
Is IC741 a hybrid ic?
no, the 741 opamp is a monolithic IC.
IC 741 is an?
It is an opamp chip consisting of 8 pins
Which of following OP amp is used to strengthen the week signal?
741 opamp
What is the applications opamp buffer circuit?
An opamp buffer circuit is one where the input signal is connected to the plus input, and the output is connected to the minus input. Within the performance limitations of the opamp, the output will track the input. The advantage of the buffer circuit is that is presents very little load impedance to the input signal, while providing a low impedance from the output to drive whatever circuitry is connected there.
What is the meaning of l in lm324?
Possibly Linear, in which case it means analog. The LM324 is an opamp.
What are the two basic configurations in operational amplifier?
opamp is a device used to amplify ac as well as DC input signals. It is called as operational amp becoz it is used to perform all mathematical operations. Symbol of opamp indicates the direction of current.
What limits output of an operational amplifier?
Feed back resistance plays the vital role of controlling output of the OPAMP. Also surrounding temperatures affects the out put of OPAMP. ANSWER: The gain drives the output to either B+ or B- minus the saturation of the output circuitry
