ADS8363EVM Application Field and Working Principle

Evaluation boards, also known as ADCs (Analog to Digital Converters), are used to convert analog signals into digital signals. The ADS8363EVM is a specific form of ADC board specifically for data transmission. It has an input of single ended or differential analog signals which is parallel to the output which is a serial digital signal. The ADS8363EVM board from Texas Instruments is a complete evaluation and design tool for customers needs.

Applications of ADS8363EVM Board:

The ADS8363EVM board is capable of sampling up to 24-bit sigma-delta analog to digital convertion. This can turn a wide range of analog signals into digital-ready signals.This board is ideal for customers looking to communicate analog signals over long distances. It is also highly suitable for industrial or commercial control applications where data transmission of record-keeping is critical. Further, this board is also suitable for medical applications such as diagnostics where accurate and precise measurements are needed.

Working Principle of the ADS8363EVM Board:

The ADS8363EVM board works by converting analog signals into digital signals through its parallel-to-serial converter. This board carries out a process called ‘Sigma-Delta Modulation’ which is a technique that involves oversampling and noise-shaping. Sigma-delta modulation begins with the input of an analog signal into the ADC board. The board then samples and quantizes the input signal over a certain period of time. This is called Oversampling and creates a continuous series of binary words that correspond to the analog signal. Noise-shaping is the process of reshaping the data points to reduce noise and produce a high quality digital signal. This is achieved by filtering signals and noise components from the signal and then remodulating the resulting signal. This is performed by the AD8366 digital filters which operate at 1 million samples per second and reduce noise by 98dB.

The ADS8363EVM board also includes an SPI interface which provides the user with control of the board. The interface can be used to control the sampling rate and noise shaping as well as enabling the input and output gain control. This will enable the user to customize the board further to suite their needs.

Conclusion

The ADS8363EVM board is a specialist ADC evaluation board for data transmission over long distances. It is fitted with Sigma-Delta Modulation capabilities through its oversampling and noise-shaping feature. This board also provides the user with SPI interface to further customize the board to the customer’s needs. ADS8363EVM board is suitable for industrial control, commercial control and medical diagnostic applications where accuracy and precision are needed.
