The term Operational Amplifier is some times shortened to OpAmp [Op Amp].

Operational Amplifier Manufacturers

An Operational Amplifier is a device which is a high gain amplifier whose gain and response characteristics are determined by external components. Normally this is a high gain linear amplifier which depends on negative feedback to achieve precise gain characteristics. The device is called an Operational Amplifier due to the fact that it's an amplifier, and because it was used to perform mathematical operations; addition, multiplication, division, integration, and differentiation.

Op Amp Terms:
Comparator; An Op Amp that is pre-configured with the component package to function as a Comparator.
JFET; An Op Amp with a high impedance FET input.
Programmable Gain; An Op Amp that accepts [digital] inputs which effect the gain of the output.
Rail to Rail; An Op Amp that switches to within a few mV of each supply voltage.

Commercial Op Amps are designed to operate over the commercial temperature range of 0 to 70 degrees centigrade.
Military Op Amps operate between the temperature range of 0 to 125 degrees centigrade and may also comply to a military standard.
Note the meaning of some terms may be specific to a particular manufacturer and not industry standard; Low noise, high speed and so on.

Design hint; Some dual supply op amps may also indicate placing one or more by-pass capacitors between the two supply voltages.
While the normal design practice is to place the capacitors between the supply voltage and ground, not between the voltages.
