The main function of an op-amp is to amplify AC and DC signals and also for mathematical operations like addition, multiplication, subtraction, etc. Based on the circuit design, Op-Amps can be configured for many applications like Amplifiers, Comparators, Integrators, Differentiators, Summer, Voltage Follower etc.. This means that if we double the frequency, gain drops by half. These op-amps are used in many applications like oscillators, comparators, filters, pulse generators and in various For a good, robust, all-around op-amp IC, get some 741 chips. The frequency compensation is provided internally to make OP-AMPs work over wide range frequencies. The op-amp greatly amplifies the difference between the two inputs, and outputs the result. The integrated circuit contains 20 transistors and 11 resistors. As mentioned earlier MC1436 is a single op-amp IC. To minimize op-amp drift, we can select an op-amp made to have minimum drift, and/or we can do our best to keep the operating temperature as stable as possible.
