Amplifier classification

Main categories of integrated operational amplifiers

The integrated operational amplifiers with different characteristics are introduced below.

The general-purpose integrated operational amplifier

A general-purpose integrated operational amplifier means that its technical parameters are relatively moderate, which can meet the requirements of use in most cases. General-purpose integrated operational amplifiers are divided into Type I, Type II, and Type III.

Type I is a low-gain operational amplifier, Type II is a medium-gain operational amplifier, and Type III is a high-gain operational amplifier. Type I and Type II are basically early products, their input offset voltage is about 2mV, and the open-loop gain is generally greater than 80dB.

The high-precision integrated operational amplifier

High-precision integrated operational amplifiers refer to operational amplifiers with small offset voltage, very small temperature drift, and very high gain and common-mode rejection ratio. The noise of this type of operational amplifier is also relatively small.

Among them, the offset voltage of the monolithic high-precision integrated operational amplifier can be as small as a few microvolts, and the temperature drift can be as small as tens of microvolts per degree Celsius.

The high-speed integrated operational amplifier

The output voltage conversion rate of the high-speed integrated operational amplifier is very large, and some can reach 2~3kV/μS.

High input impedance integrated operational amplifier

The input impedance of the high input impedance integrated operational amplifier is very large, and the input current is very small. The input stage of this kind of operational amplifier often adopts a MOS tube.

The low-power integrated operational amplifier

The current of the low-power integrated operational amplifier is very small and the power supply voltage is also very low. The power consumption of the entire operational amplifier is only tens of microwatts. This type of integrated operational amplifier is mostly used in portable electronic products.

Broadband integrated operational amplifier

Broadband-integrated operational amplifiers have a very wide frequency band, and their unity-gain bandwidth can reach more than gigahertz. They are often used in broadband amplifier circuits.

The high-voltage integrated operational amplifier

Generally, the supply voltage of integrated operational amplifiers is below 15V, while the supply voltage of high-voltage integrated operational amplifiers can reach tens of volts.

Power-integrated operational amplifier

The output stage of the power-integrated operational amplifier can provide a relatively large power output to the load.

Optical fiber amplifier

Optical fiber amplifiers can not only directly amplify optical signals, but also have real-time, high-gain, broadband, online, low-noise, and low-loss all-optical amplification functions. It is an indispensable key component in a new generation of optical fiber communication systems;
