Furthermore, the device is designed to help meet the stringent accuracy and noise requirements of specialised applications, such as those in the defence industry.

Working Principle

The ADS6425IRGC25 device operates using a two-step conversion process. In the first step, the incoming analog signal is converted into a digital representation by the analog-to-digital converter. This digital representation is then used to feed a digital filter within the ASIC. The output of the digital filter is then passed through a digital-to-analog converter, resulting in a clean, low-noise digital representation of the incoming analog signal.

The entire conversion process is designed with a purpose-tuned architecture to help reduce overall power consumption and provide ultra-low distortion performance. The combination of the two-step conversion process and the advanced architecture enables the device to achieve conversion speeds of up to 3.2Msps with a low conversion power of 0.7mW. Additionally, the device provides a high SNR (Signal-to-Noise ratio) of 89dB and a THD (Total Harmonic Distortion) of -100dB.

The ADS6425IRGC25 device is also programmable, enabling users to configure the device for their specific application. Various register settings are available to enable different modes such as continuous sampling rate, toggling, and looping. Additionally, the device offers selectable reference levels and a wide range of data rates for a variety of user-specified needs.

Conclusion

The ADS6425IRGC25 ADC provides a wide range of features that can be used to meet virtually any analog-to-digital conversion requirement. Its exceptional speed, low power consumption, high resolution, and dynamic range make it an ideal choice for many applications. Additionally, its programmable capabilities make it adaptable to a wide range of user-specific needs. The ADS6425IRGC25 is an ideal choice for applications requiring high-speed, reliable, and accurate analog-to-digital conversion.
