Isolation AmplifiersIsolation amplifiers are a type of amplifier that are used to provide electrical isolation between the input and output of the amplifier. This is achieved using a transformer or optocoupler to create a physical barrier between the two sides of the amplifier, which prevents any electrical current from flowing between the input and output. Isolation amplifiers are commonly used in RF circuits to prevent ground loops and other common-mode interference from affecting the amplified signal. They are also used to protect sensitive electronic equipment from electrical surges or other harmful effects. Isolation amplifiers are an important part of many RF circuits, and are used in a variety of applications, including medical imaging, industrial automation, and electrical power systems.
