Classification of operational amplifiers

1. Universal integrated operational amplifier

Universal integrated operational amplifiers refer to those with relatively moderate technical parameters that can meet most usage requirements, and are divided into Type I (low gain operational amplifiers), Type II (medium gain operational amplifiers), and Type III (high gain operational amplifiers).

2. High-precision integrated operational amplifier

High precision integrated operational amplifier refers to an operational amplifier with low offset voltage, low temperature drift, and high gain and common mode rejection ratio. This type of operational amplifier also has low noise.

3. High speed integrated operational amplifier

The main characteristics of high-speed operational amplifiers are high conversion rate and wide frequency response, which are commonly used in fast A/D and D/A converters and video amplifiers.

4. Low power integrated operational amplifier

Low power integrated operational amplifiers have low current, low power supply voltage, and a power consumption of only a few tens of microwatts, commonly used in portable electronic products.

5. High input impedance integrated operational amplifier

High input impedance integrated operational amplifiers have high input impedance and low input current, and the input stage often uses MOS transistors.

6. Broadband integrated operational amplifier

The characteristic of a broadband integrated operational amplifier is its wide bandwidth, with a unit gain bandwidth of over gigahertz, commonly used in broadband amplification circuits.

7. Power type integrated operational amplifier

The output stage of a power type integrated operational amplifier can provide a larger power output for the load.

8. High voltage integrated operational amplifier

Generally speaking, the output voltage of operational amplifiers is mainly limited by the power supply, while high-voltage integrated operational amplifiers can output high voltage and large current without the need for additional circuits.

9. Low temperature drift type operational amplifier

The offset voltage of the low-temperature drift type operational amplifier is small and will not change with the low-temperature environment.

10. Programmable control operational amplifier

The use of instruments and meters often involves the issue of range. In order to obtain a fixed voltage output, it is necessary to change the amplification factor of the operational amplifier. Programmable control operational amplifiers are designed for this purpose.
