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.
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.

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 has the author Vithoon Pongparit written?
Vithoon Pongparit has written: 'On the rational approximations to the ideal delay function and their time-domain optimization' -- subject(s): Delay lines
When was East Journal on Approximations created?
East Journal on Approximations was created in 1995.
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
Where is the ground on an operational amplifier?
An opamp has a ground terminal on one of the pins.
Which of following OP amp is used to strengthen the week signal?
741 opamp
What is the approximations for pi?
3.14 and 3.14159 are two commonly used decimal approximations. In ratio form, 22/7 is often used.
What are characteristics of an ideal diode?
An ideal diode:Passes current in one direction only. (Under forward bias).Has no leakage current (passes no current under reverse bias).Has no forward voltage drop. (No voltage loss under forward bias - a real diode has Vd~=0.7)See links for more details.
