Working Principle

The ISL26104AVZ-T operates on the sigma-delta principle, which is an oversampling technique. This technique uses an analog-to-digital conversion technique that samples a signal at a much higher rate than the Nyquist rate, which is the minimum sample rate needed to accurately represent a given band of frequencies. In this process, the signal is first sampled at a much higher rate than what is normally required; a process known as oversampling. The resulting digital signal is then filtered to obtain a digital representation of the original analog input.

This method is extremely efficient and provides accurate conversion with a low power footprint. The sigma-delta technique achieves high accuracy and dynamic range with a minimum of external components. This makes it ideal for applications where power consumption and component count are critical.

Conclusion

The ISL26104AVZ-T is an ultra-low power, multi-channel sigma-delta analog-to-digital converter. Its wide range of features, low power consumption, and high precision make it well suited for use in a variety of applications, such as medical imaging, patient monitoring, automotive, and industrial automation. Its sigma-delta conversion technique enables it to provide efficient and accurate conversion with a minimum of external components; making it an ideal choice for low-power applications.
