Data Acquisition - Analog to Digital Converters (ADC) is an important part of electronic information processing. In electronic products, analog signals must first be converted into digital signals for further processing. The AD7273BRMZ is a high-performance analog-to-digital converter chip designed for precision signal conversion. This chip contains features such as low power consumption, high speed and low noise. It is an ideal device for signal processing application.

AD7273BRMZ belongs to the A/D converter device, it is the A/D converter with the resolution of 12 bits, and the sampling rate of up to 5 million samples per second, so it can be used in many kinds of application fields. For example, it can be used in medical instrumentation, data acquisition, industrial control and process control etc.

The working principle of the chip contains three parts: reference conversion, analog input conversion and digital output.

The reference conversion involved is responsible for providing stable and accurate reference voltage to the A/D converter, which is the precondition for A/D conversion. The reference conversion is divided into three parts: reference voltage selection, reference voltage amplifier and reference voltage decoupling. The reference voltage selection is used to select the reference conversion accuracy of the A/D converter, the reference voltage amplifier is used to amplify and stabilize the selected reference voltage, and the reference voltage decoupling is used to eliminate the noise coupled to the reference voltage. The reference conversion is one of the important factors for ensuring the accuracy of the A/D converter.

The analog input conversion is the most important part of the A/D conversion; it is the operation process of A/D conversion from the analog voltage applied to the analog input port to the digital output obtained. Generally, the analog input conversion is based on the successive approximation principle. The successive approximation principle is an iterative method based on binary search, which compares the sample to the known reference voltage. After each iteration, the comparison results are used to select the next reference voltage, until the sample is exactly equal to the reference voltage, that is, the sample is converted into digital values. This is how the analog-digital conversion works.

Finally, the digital output part of AD7273BRMZ is also very simple. The processor acquires the binary codes obtained from each sample by successive approximation principles from the analog input port. After the sample is converted into a digital code, the digital output port of the chip will output the digital code.

In summary, AD7273BRMZ can be used by many different types of applications concerning data acquisition and signal processing. With its low power consumption, high speed and low noise characteristics, it makes an ideal choice for most applications. Furthermore, the precision and accuracy of the A/D conversion is also guaranteed thanks to its reference conversion, analog input conversion and digital output parts.
