What is Op-Amp non inverting amplifier?
When the feedback of the output terminal of an Op-Amp is given to the non-inverting terminal [pin 3 for IC-741] of that Op-Amp , then , that circuit is called non-inverting amplifier using Op-Amp. This circuit is called non-inverting because the output signal of this circuit is in phase with the input signal.
What type of feedback is used in inverting and non inverting op amp amplifier?
positive in inverting and negative in non inverting
Why is non inverting summing amplifier using op amp not used?
It is not true. The non-inverting summing amplifier is used all the time. It is an excellent Analog Signal Processing circuit. As an example, the bipolar to unipolar converter can be designed with a non-inverting summing amplifier.See Related links below for more information.

How do you calculate gain of an inverting and non-inverting OP-Amp configuration?
gain in an op-amp is the output voltage divided by input voltage. for the inverting amplifier , gain(Av)=-(Rf/Ri) ,where Rf => resistance of the feedback path & Ri=> inverting input terminal resistance for the non-inverting amplifier , gain(Av)=(1+(Rf/Ri)) , where Rf => same & Ri=> non inverting input terminal resisance
Why you used inverting op amp more than non inverting op amp?
since gain is simply -Rf/Ri and is 1+Rf/Ri in case of non inverting
What is input impedance of op-amp?
III LM324 Non-inverting AC Amplifier Circuit R1 and R2 form a 1/2V+ voltage divider circuit, which biases the op-amp through R3. The circuit input resistance is R3, and the resistance of R4 ranges from several thousand ohms to tens of thousands of ohms.
What amplifier circuit is typically used as the input stage for an operational amplifier?
Differential amplifier ANSWER: A differential amplifier is an op amp. If any amplification is required a preamplifier is used mainly to cut the white noise and improve the input impedance
What is meant by non inverting amplifier?
There is no such thing as an inverting or a non-inverting op amp.All op amps have both an inverting input and a non-inverting input. Their operation is such that the output will go to whatever value is required to make both inputs be the same. This implies feedback from output to inverting input.

How does the operational amplifier work?
The operational amplifier is a device with two inputs, and one output. One input is called non-inverting, while the other is called inverting. Sometimes, there are two outputs, in which case one is also non-inverting and the other inverting. Within the limits of the design of the operational amplifier and its circuit, the output will assume whatever state is necessary to make the two inputs equal to each other. The output goes in the same direction as the non-inverting input, or in the opposite direction as the inverting input. Note that for the operational amplifer to work correctly, there needs to be some kind of feedback loop, usually from output to inverting input (we call this negative feedback), so that the output can track one of the two inputs in the ratio of the bridge that is setup in the circuit design.
Investigate filter circuit using operational amplifier?
A filter can be designed using an op amp by by replacing the resistors in an inverting or non-inverting amplifier with inductors or capacitors. Search for "op amp" on wikipedia for some simple schematics as a starting place. If you understand the basics of filter output and bode plot calculations, you should be able to replace R1 or R2 with C1 (1/jC1w) or L1 (jwL), and analyze the output vs. input characteristic.Note op amps have limitations on frequency response, so this approach is good for fairly low frequencies - if you get into the high MHz, or GHz, a passive filter circuit becomes necessary.
