Instrumentation, OP Amps, Buffer AmpsInstrumentation amplifiers, operational amplifiers (op amps), and buffer amplifiers are all types of integrated circuits (ICs) that are used to amplify or otherwise manipulate electrical signals. Instrumentation amplifiers are a type of differential amplifier that is designed to amplify small, low-level signals in a precise and accurate manner. They are commonly used in applications such as medical instrumentation, test and measurement equipment, and industrial process control. Op amps are a type of voltage amplifier that is designed to provide high gain and high bandwidth, and are commonly used in a wide range of analog circuits and systems. Buffer amps, also known as unity gain amplifiers, are a type of amplifier that is designed to provide high output impedance and low input impedance, and are often used to isolate or buffer a circuit from other circuits in a system.
