Working Principle

The ADC102S021CIMMX/NOPB operates using a successive approximation register (SAR) architecture. This architecture is based on the input voltage being compared to a reference and a series of comparators. As the reference increases, the comparators will either return a logic high or low, depending on the state of the analog input voltage. This process is repeated until the input voltage has been accurately measured, and the 12-bit output is obtained.

In addition, the device features programmable features such as sample rate, input range, and output resolution. These features make the ADC102S021CIMMX/NOPB well-suited for applications with varying input voltages and time periods. This means that the device can be easily optimized to meet the specific requirements of the application.

Conclusion

In conclusion, the ADC102S021CIMMX/NOPB is an excellent choice for a variety of applications. This cost effective device is small, low power, and highly accurate. Its wide range of features and flexible design make it a great choice for embedded, communications, industrial, and consumer applications. In addition, its capability to be switched between multiple resolutions and sample rates enable it to provide reliable and consistent performance.
