You can get it at your local swap meet if you are looking to save a quick dollar, or you can go ahead and treat yourself to a nice one online and have it shipped to your doorstep.
It has several but one of the main ones is that it has built in frequency compensation, which its predecessor the 709 operational amplifier did not.
An opamp has a ground terminal on one of the pins.
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .
design and implementation of a buffer circuit using operational amplifier
Originally such an amplifier did mathematical functions.
The LM358 is an operational amplifier.
Operational amplifiers are usually bought as an I.C., but they may be constructed with discrete components too.
