What is the name of op-amp circuit which results in the difference of the 2 input signal?
Differential Amplifier
Differential Amplifier The circuit operates from a dual supply +Vcc and -Vee which ensures a constant supply. The voltage that appears at the output, Vout of the amplifier is the difference between the two input signals as the two base inputs are in anti-phase with each other.
How do I know what op-amp I need?
Op amp requirements The ideal op amp, should it ever exist, would have infinite gain, infinite input impedance, zero output impedance, it should have an infinite frequency response, not introduce any noise, and it should be distortion free. Obviously no op amp can meet all these requirements.

Why it is called IC 723?
The 723 voltage regulator is commonly used for series voltage regulator applications. It can be used as both positive and negative voltage regulator. It has an ability to provide up to 150 mA of current to the load, but this can be increased more than 10A by using power transistors.
Is the op-amp a closed loop or differential amplifier?
In other words, the op-amp becomes a “differential amplifier”. In this Inverting Amplifier circuit the operational amplifier is connected with feedback to produce a closed loop operation.
How to choose the best op-amp for your application?
There are probably thousands of operational amplifiers (op-amps) available. But which one is the best for your particular application? A datasheet has lots of numbers and graphs, and then there are the many strange acronyms. This article will show you how to wade through the jargon and select the op-amp that best fits your needs.
What’s the difference between an op amp and a comparator?
In terms of the basic circuit operation, the main difference is that most comparators have an open collector output and require an external pull-up resistor or other circuity. Operational amplifiers are very cheap, and very widely available.
What are the different types of op amps?
The first is that we will only examine basic op-amps. We will not look directly at special types, like high frequency (10s to 100s of MHz), current-difference, or trans-conductance. However, once the basic op-amp is understood, it is a small step to the special types.
