Application Field

The XRD8799EVAL evaluation board can be used in a wide range of applications. It can be used to test and develop the performance of a wide range of Analog-to-Digital Converters (ADCs), including accelerometers, digital thermometers, and other temperature or pressure measuring devices. The board is also suitable for medical imaging and remote sensing applications. It can provide high resolution and low noise to measure the parameters in these applications.

Working Principle

The XRD8799EVAL evaluation board is driven by the XRD8799 integrated circuit chip. It includes two major components: the XRD8799 24-bit sigma delta ADC and the XR2211 charge pump with its modulation frequency generator. The sigma delta ADC uses a delta-sigma loop to convert the analog input signal into a digital signal. The charge pump modulates the frequency generator to generate signal that is used to control the sigma-delta loop. This modulation provides additional noise shaping, reducing out-of-band noise and eliminating the need for external antialiasing filters. The operational amplifier on the board amplifies the analog input signal to the accurate voltage scale. The amplifier also filters noise and offers gain adjustment capabilities. Finally, several support components provide additional support to the board, helping it achieve optimum accuracy and performance.

Conclusion

The XRD8799EVAL evaluation board is a powerful evaluation platform for Analog to Digital Converters (ADCs). It is suitable for automotive, industrial control, medical imaging and remote sensing applications. The board is powered by the XRD8799 chip, which consists of an integrated sigma-delta ADC and a charge pump with its modulation frequency generator. It is aided by an operational amplifier and several support components, which provide additional noise shaping capabilities and maximise accuracy.
