An analog front-end (AFE) is a set of analog signal conditioning circuitry that uses operational amplifiers, filters, and sometimes application-specific integrated circuits for sensors and other circuits to provide 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. AFE hardware modules are used as to interface sensors of many kinds to digital systems, providing hardware modularity. For example, Texas Instruments markets health monitoring AFEs as the ADS1298, AFE4400 and AFE4490. A radio frequency AFE is used in radio receivers, known as an RF front end. Atmel markets analog front-ends for smart meters. Analog Devices markets a CN209 product for test and measurement applications. == References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Analog front-end」の詳細全文を読む スポンサード リンク
