Data Acquisition System ICs

A Data Acquisition System, commonly abbreviated to DAS or DAQ, is a device that measures analogue electrical signals and converts them into digital form. The translation of analogue signals into digital provides data in a binary format that can be stored, read and processed by a computing system.

For example, a Data Acquisition System is commonly used to process the signals produced by sensors. A sensor monitors a physical phenomenon, producing an analogue output proportional to the variable being measured. A Data Acquisition System can be used to convert the signal into digital, allowing it to be used by the host system.

To provide complete analogue-to-digital conversion functionality a Data Acquisition System IC integrates all the required circuity into one device, marrying an analogue front-end (AFE) signal conditioning circuit to an analogue-to-digital converter in one package.

Signal conditioning circuity prepares the analogue input for processing, as often raw input signals are not suitable for processing by the analogue-to-digital converter. Filtering, amplification, isolation and attenuation are some examples of the conditioning circuity that may be integrated into the device.

Why use a Digital Acquisition System IC for Signal Conversion?

• A DAS IC provides a complete signal conversion solution, it minimises the external circuity required. Component count is less compared to utilising standalone analogue to digital converters with separate signal conditioning circuits
• Product development is simpler as all of the needed conversion functionality is already designed and provided by the device.
• Can be more space efficient and take up less PCB space
