Introduction

ADAU1979WBCPZ-RL is a high performance, analogue to digital converter (ADC) that is suitable for many applications ranging from data acquisition systems to motor control systems. The ADC is designed to work in tandem with the microcontroller-based system including the general-purpose input/output (GPIO) boards. This way, the ADC and microcontroller can be used to trigger and control the actions of other components on the board. The ADC is designed with a wide range of operating voltage levels, from 0.1V to 6V, and is available in 8, 10 and 12-bit resolutions.

Application Field

The ADAU1979WBCPZ-RL can be used for data acquisition systems such as industrial process controllers, real-time motor control systems, and embedded applications. Additionally, it can be used as an analog input controller for many sensing, health and environmental systems. Due to its wide range of operating voltages, the ADC can be used in many different applications requiring a precise, accurate and reliable data acquisition system. With its wide range of resolutions, it can be used in applications where a high sampling rate is needed, such as in high speed imaging systems. In addition, due to its small size and low power consumption, it can be used in portable applications such as data loggers and test and measurement systems.

Working Principle

The working principle of the ADAU1979WBCPZ-RL is as follows. The device consists of an analog input stage, an ADC, and a precision time base. The analog input stage is responsible for pre-conditioning the analog signal and converting it to a voltage that the ADC can recognize. This is done by utilizing a wide range of low-pass, high-pass, and band-pass filters. The ADC then converts the analog signal into digital data using its sampling process. The ADC consists of a sample and hold amplifier, followed by an analog-to-digital converter. The sample and hold amplifier is responsible for sampling the input signal at regular intervals and converting it into a digital representation. The analog-to-digital converter then converts the digital samples into a digital output.Finally, the precision time base is responsible for supplying the ADC with regularly-spaced clock pulses for initiating the samples. This clock can be derived from an external source or from the ADC itself.

Conclusion

In conclusion, the ADAU1979WBCPZ-RL is ideal for many data acquisition applications due to its wide range of operating voltage levels and its excellent performance in high-speed imaging systems. Its wide range of resolutions makes it suitable for many different applications. Additionally, due to its small size and low power consumption, it can be used in portable applications such as data loggers and test and measurement systems.
