Analog Front End (AFE)An analog front end (AFE) is a type of integrated circuit (IC) that is used in data acquisition systems to interface with analog signals. An AFE typically consists of a set of amplifiers, filters, and other signal processing circuits that are designed to condition analog signals for further processing by a digital system. AFEs are commonly used in applications such as medical imaging, industrial automation, and scientific instrumentation, where they are used to convert analog signals from sensors or other sources into a form that can be easily processed by a computer or other digital system.
