OPAMPS with practicals

An Operational Amplifier or op-amp is a voltage amplifying device designed to be used with external feedback components such as resistors and capacitors between its output and input terminals. It is a high-gain electronic voltage amplifier with a differential input and usually a single-ended output. Op-amps are among the most widely used electronic devices today, being used in a vast array of consumer, industrial, and scientific devices.

OPAMPS are mainly available in these 3 most popular pinouts. You can see them below. You can have a long list of opamps available in microchip,TI,ST and analog devices website. Most of them are available in one of these 3 packages. However in the 741 type pinout ICs, pins 1 and 5 may have other functions like offset null, compensation capacitors, etc. However more smaller packages(QFP) have differnt pinouts. Below pic shows only for DIP and SMD(if available) configurations. And for a practical testing and product making, having the knowledge of common opamps and their 3 types of pinouts (as in the pic below) are enough. However one should always check datasheet before using any opamp.
