Analog front-end

Analog Front End.

A relative new concept in analog signal conditioning circuitry that uses operational amplifiers, filters, ASIC (Application-specific integrated circuit) for sensors and other circuits to provides a configurable and flexible electronics functional block, needed to interface a variety of sensors to an analog to digital converter or in some cases to a microcontroller o digital systems.

AFE's could be considered as hardware modules to interface sensors of many kinds to digital systems, providing hardware modularity, for example a medical AFE from Texas Instruments.
