Operational Amplifier
An operational amplifier is one of the basic building blocks for analog circuits, An operational amplifier takes in differential voltage input and produces a single-ended voltage output. The basic purpose of employing an operational amplifier in an analog circuit is to perform the function of signal amplification: The process of boosting an electrical signal of low strength to a level of higher amplitude. Op-amps also function as a filter of the input signal; meaning that, an operational amplifier is able to extract the signal with the target frequency. Op-amps can be divided into two fundamental parts:
- Precision Op-amps
- Differential Op-amps
