Beginners Guide to the Op-Amp

Operational amplifiers are amongst the most widely used electronic devices today. They are so common that most involved in their use, electrical engineers and some designers, often take them for granted. Without them, however, an amplifying voltage for use in audio, video, and applications would be exceptionally more challenging. Regardless of the configuration of the Op-amp (it’s generally configured to specific applications) they are one of the most integral components in analog circuitry. One of the best sites out there to explain this technology is Microchip.

Making sure you have the right configuration, and the right op amp within that configuration can make significant differences in the end product.

The usual configurations of operational amplifiers you’ll run into are:

Precision op-amps

These operational amplifiers are used to make accurate DC and AC currents in precision circuits. These are used in zero drift and low noise amplifiers. This technology is integral to medical instruments, electronic equipment, and radio communications systems.

High-speed circuits

These circuits allow for performances from 50 MHz to 8 GHz while simultaneously lessen the expenditure of power. These can be used in practices like Radio-frequency engineering, high-speed data acquisition, and high-speed communications.

Ultra-low-power op-amps

These are what can give devices a lasting power supply without needing to change batteries or receive a charge.  They work to expand the power-to-performance ratio in a multitude of devices and make many modern types of technology possible.

Audio op-amps

These op amps specialize in low distortion to increase the sound quality. It’s important to balance a low power need with a clean audio output, and audio op amps attempt to strike that balance.

Power op-amps

These are higher current and voltage amps used to power designs, Ideal for industrial and automotive applications. These op amps usually try to pack the biggest punch inside of the smallest package.
