Data acquisition is the process of measuring an amount of physical data and transferring it to an electronic device for recording and analysis. Digital potentiometers, or DS3903E-020+T&R, are electronics components used to measure physical parameters such as resistance, capacitance, and voltage. In this article, we will discuss the application field and working principle of DS3903E-020+T&R.

The DS3903E-020+T&R is well suited for application fields including automotive electronics, environmental conditions, and power runs. Automotive electronics require reliable and accurate measurements of power and voltage levels as they must communicate with the vehicle’s electrical system. DS3903E-020+T&R helps to measure these power and voltage levels with great accuracy. Similarly, environmental conditions must be monitored in order to maintain the optimum environment for optimal performance. DS3903E-020+T&R helps to acquire these data with accurate measurements. Lastly, in power runs, precise measurements of the current consumed by each component is important. DS3903E-020+T&R helps to measure these current levels with great accuracy.

As far as the working principle is concerned, the DS3903E-020+T&R digital potentiometer is a three-terminal, digital-to-analog converter (DAC) with a high precision ratiometric-return terminal output. Its three-terminal structure consists of the Digital Input (DI), Analog Output (AO), and Digital Brown Out (DBO) terminals. The Digital Input terminal is used to program the digital potentiometer. The Analog Output terminal is an analog output voltage generated by the DBO terminal, which can be used to measure the DC, AC, and audio signals. The Digital Brown Out terminal is used to generate the DC voltage that changes with the input signal.

The working of the DS3903E-020+T&R digital potentiometer is quite simple. When a voltage signal is applied to the Digital Input terminal, the resistance between DI and AO terminals changes, thus varying the output voltage. The Digital Brown Out terminal is used to detect the resistance value by comparing the input voltage with the output voltage. The Digital Brown Out terminal then determines the resistance and adjusts the output voltage according to the input voltage.

In conclusion, DS3903E-020+T&R digital potentiometers are an excellent choice for data acquisition applications such as automotive electronics, environmental conditions and power runs. They offer excellent accuracy and reliability, and their simple working principle allows them to be easily implemented in any application.
