Working Principle

The ADC14DS080CISQE/NOPB works on the principle of converting an analog signal into digital signal. It uses on-chip reference and offset adjustment, dual 14-bit monolithic sampling converter, and two-channel simultaneous conversion to achieve this. During conversion, the ADC assigns digital codes to different voltage levels based on the input signal and provides a digital representation as output. Once the analog signal is converted, it can then be processed and used for various purposes.

The ADC14DS080CISQE/NOPB works in both single and dual-edge sampling modes. In single-edge sampling, the input signal must be applied to the input of the ADC. The reference voltage is then used to process the signal and convert it into digital codes. In dual-edge sampling, the computer combines the two channels of the ADC to create higher resolution. The output of this ADC is linear, which means that the digital number is linearly proportional to the input analog signal.

Conclusion

The ADC14DS080CISQE/NOPB is a dual 14-bit sampling converter designed for low-power and high-speed performance. It features on-chip reference and offset adjustments, dual-edge and single-edge sampling modes, and a low-maintenance pipeline latency. This ADC provides a 1.4 nV/√Hz input capacity and has a power consumption of less than 0.2 mW/channel. It is widely used in industrial and consumer applications such as automotive, computer, communications, and medical systems.
