Generally, an amplifier is any device that will convert a signal with a small amount of energy into a similar signal with a larger amount of energy. In popular use, the term today usually refers to an electronic amplifier, often as in audio...

Name the amplifier (op amps, digital amplifiers, servo amplifiers, and power amplifiers)and you'll find dramatic performance gains thanks to circuit design improvements and advances in semiconductor processing technologies. Lower power consumption, smaller package sizes, faster slew rates. wider bandwidths, and lower noise levels...

The most conspicuous trend in amplifiers is the list of new features that I help systems engineers who aren't entrenched analog specialists avoid catastrophic design errors. Consider how it demolishes a system-development schedule when an amplifier that worked perfectly on the bench does...
