1.According to the parameters of the integrated operational amplifier, and the integrated operational amplifier can be divided into the following categories :

1 ) Universal Operational Amplifier.

2 ) High Resistance Operational Amplifier.

3 ) Low Temperature Drift Operational Amplifier.

4 ) High Speed Operational Amplifier.

5 ) Low Power Operational Amplifier.

6 ) High Voltage High Power Operational Amplifier.

2. The mode of power supply :

Integrated operational amplifier of power supply mode is symmetrical double power supply mode and single power supply mode.

( 1 ) Double power supply is powered by symmetrical double power supply mode.

The positive power supply ( + E ) and the negative supply ( -E ) of the public end ( ground ) are respectively connected to the VCC and VEE pins of the operational amplifier. In this way, the signal source can be directly connected to the input pin of the operational amplifier, and the amplitude of the output voltage can be close to the positive and negative symmetrical supply voltage.

( 2 ) Single supply is to connect the VEE pin of the op amp to the ground. At this time, in order to ensure that the internal unit circuit of the operational amplifier has an appropriate static operating point, a stable DC potential must be added to the operational amplifier. At this time, the output of the operational amplifier changes with the input signal on the basis of the DC potential.
