OP275 is a dual JFET operational amplifier. It is the first amplifier to feature the Butler Amplifier front-end. This new front-end design combines both bipolar and JFET transistors to attain amplifiers with the accuracy and low noise performance of bipolar transistors, and the speed and sound quality of JFETs. Total Harmonic Distortion plus Noise equals that of previous audio amplifiers but at much lower supply currents.
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
