Analog-to-Digital Converters (ADCs) are devices used to transform analog signals into digital ones. The ADS900E ADC is one of the most popular ADCs used in a variety of applications, such as industrial, automotive, video, and medical applications.

The ADS900E is a cost-efficient 24-bit delta-sigma ADC with a 17-bit effective resolution. It has a dynamic range of up to 114 dB and a signal-to-noise ration (SNR) of 114 dB. It boasts a high-speed throughput of 48 Ksps and a low noise floor of -90 dBFS. The ADS900E is also equipped with a wide power-supply range of 4.5 V to 28 V.

The key features of the ADS900E include a 62nV/√Hz input referred noise, excellent dynamic performance, and low power consumption. It also has on-chip interpolation filters that provide high-order anti-aliasing. The device has a built-in low-jitter clock buffer, allowing it to be synchronized with an external microcontroller.

The ADS900E is a highly integrated device with built-in calibration for performance optimization. It has a unique 16-bit format with an additional 8-bit redundancy that enables it to reliably detect errors. Furthermore, the device has an on-chip EEG pre-processing feature to reduce noise in EEG signal, and it has a dynamic range selection function that allows it to handle signal of different amplitude ranges.

The working principle of the ADS900E is simple yet powerful. It starts by converting an incoming analog signal into a digital signal. The signal is then converted into a low-frequency voltage signal using delta-sigma modulation. This signal is then digitized by an analog-to-digital converter, resulting in a digital representation of the input signal.

The ADS900E is also equipped with on-chip filtering and decimation techniques to reduce noise levels. The filtered and decimated data is further processed by applying a variety of data conversion techniques, such as interpolation, averaging, and digital signal processing. The end result is a highly reliable digital signal that can be used for various applications.

The ADS900E is highly compatible with a wide range of applications, such as medical instrumentation, automotive, and consumer audio applications. It is also suitable for high-speed signal processing of analog signals. This ADC is suitable for a wide variety of signal amplitudes and signal frequencies, making it an excellent choice for different applications.

Overall, the ADS900E is a cost-effective and feature-rich ADC that has been designed to be versatile and reliable. Its wide array of features makes it suitable for a variety of applications, including medical, automotive, and consumer audio applications.
