A data acquisition device, analog front end (AFE), is a sophisticated semiconductor component used to condition signals that contain analog amplifiers, filters, integrated circuits, ICs, and op amps. This functional block, configured in nature, is built to interface with various sensors. Resolution options vary from 8 to 42 bits, and the number of channels available ranges between 1 and 256
Data Acquisition - Analog Front End (AFE): Overview
An Analog Front End is an indispensable device used in data acquisition systems. Its primary function is interfacing analog signals to digital systems, providing efficient conditioning for convenient signal conversion. AFEs are utilised to perform various tasks, such as filtering, conversion to digital and amplification of signals, as they are fundamental components for converting real-world analog signals to digital data. These devices help businesses and technologies make wise decisions to improve data integrity and system performance.
What is the Analog Front End Used for?
Analog Front End is a system where analog signals are processed before being passed on to the digital processing unit. AFEs generally consist of components such as analog-to-digital converters (ADCs), filters, amplifiers, and often digital-to-analog converters (DACs). They are created to optimise analog signals for convenient analog-to-digital conversion.
Some of the critical functions of AFEs include:
- Amplifies weak signals to a suitable processing level.
- Eliminates noise or unnecessary frequencies from the signal.
- Convert analog signals into digital data.
- Enhancing signal quality by ensuring the impedance between the source and the AFE is correctly balanced.
