A: An op amp will have the capability to drive a load equivalent to its maximum output if more current is tried to for out the last stage will saturate causing malfunction of the circuit but if not sustained for too long it need not be catastrophic reducing the load can restore the op amp because of its protective design.
What else can I help you with?
What is the use of offset null in an opamp?
A: Any offset whether is voltage or current is an output error to contend with.
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].
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
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.
Give the definition of output offset voltage of Op-Amp?
The output voltage of a opamp when the input of inverting and non inverting terminals are grounded
Why output impedence is high in opamp?
Output impedance in an op-amp is not high - it is low - input impendance is high, and this is because the input stage transistors have high gain.
How do you bias a current mirror opamp?
If you go to the given link you will see the circuit of a current mirror using Op-Amp. And you can easily see how it is biased.
What are application of ic 741 opamp?
A 741 Op-amp has three distinct parts and applications. They are a differential amplifier, a voltage amplifier, and an output amplifier.
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 is difference between output current and pulse current?
It is a language in electronics describing whether the output is a pulse or direct current for any output.
Why input current of USis less than Output current?
Why input current of USis less than Output current?
What is output short circuit current?
The output short circuit current is the solar cell's current when the voltage is zero, or when it, is short circuited.
