ADS8481EVM

The Analog-to-Digital (ADC) conversion process quantizes an analog signal, measured continuously in the time domain, into digital values representing the signal at discrete points in time. This is a critical component in any embedded system, as it allows for the desired input information to be used in more meaningful ways. Analog Devices’ family of evaluation boards—the ADS848x family—feature a comprehensive selection of ADCs with a variety of accuracy and speed. The ADS8481EVM Board is the perfect choice for evaluating the performance of Analog Devices’ high performance, low power precision analog-to-digital converters.

The ADS8481EVM application field is broad and includes, among other areas, audio/video, industrial control, healthcare, instrumentation, automotive, and machine to machine (M2M) applications. In the Audio/video application, the analog-to-digital converter is used to convert analog audio signals into digital represented data for either audio/video encoding/decoding. For industrial control applications, the ADC is used to control industrial processes as well as measure physical parameters such as temperature or pressure. In the healthcare industry, the ADC is used for medical imaging and diagnostics. For instrumentation applications, the ADC can be used to measure system parameters such as frequency, voltage, and current levels so that adjustments and/or calibrations can be made to optimize system performance.

The working principle of theADS8481EVM is based on the conversion of an analog input signal into a digital output. The conversion process starts with an analog input signal, sent into one of the eight ADC channels. Once the signal is received, it is converted to a digital representation of the signal by performing a sampling process, then subjected to an analog-to-digital transformation. The ADC then performs additional digital processing steps such as filtering, decimation, resolution, and dynamic range adjustment, before finally outputting the converted signal. This digital output signal can then be processed and interpreted in a meaningful way by the receiving device, which is usually a microcontroller for embedded applications.

The ADS8481EVM board offers board-level features to optimize development and evaluation. This includes a comprehensive software package that helps streamline the software development process.
