Operational Amplifier

Operational Amplifier (Op-Amp) is a differential amplifier into a high trailer directly.

Op Amp is a circuit that generates the output voltage V0, which is the result of the strengthening of the difference in the two input voltages V1 and V2.

Op-Amp Characteristics
Acquisition of infinite voltage.
Bandwidth is not infinite.
Enter an infinite impedance.
Out zero impedance.
Complete balance sheet, which is zero if the output voltages at the same time there are two input terminals.
Characteristics are not changed by temperature.
