Data Acquisition - Digital Potentiometers are widely used as a way of accurately controlling voltage and current drive circuits. The AD5282BRU200-REEL7 is one such product that has proven itself invaluable in a variety of applications.

A key feature of the AD5282BRU200-REEL7 is that it has an operating temperature range of -20°C to +85°C and a tolerance of +/- 50 ppm/°C. It also has an impressive 6-bit digital resolution I2C interface which allows its output voltage to be adjusted in 64 equal incremental steps throughout its range. The digital interface is bidirectional with three-wire functionality, allowing digital control of the devices via commands over the I2C interface. It therefore allows digital potentiometers to easily incorporate into automated test systems in various applications.

In terms of its applications, the AD5282BRU200-REEL7 can be used in digital volume control systems, cellular phone audio systems, headphone amplifiers, and audio equalizers. It can also be used within digital power supplies and battery-powered applications where its bidirectional characteristics allow for precise monitoring and control. As an example, the AD5282BRU200-REEL7 can be used to adjust the voltage set-point of a voltage regulator in order to optimize the power consumption level.

The fundamental working principle of the AD5282BRU200-REEL7 is the voltage divider principle. The device is a two-terminal device that contains a resistive element which is connected to a terminal at one end and a slider at the other. The slider is connected to a central point on the resistive element. When the slider is moved along the resistive element, the potentiometer’s central point voltage changes and the voltage at the terminal end of the resistive element is adjusted accordingly. By using the I2C interface, the amount of resistance at the central point of the element can be adjusted, allowing the desired output voltage to be accurately adjusted.

The AD5282BRU200-REEL7 is therefore an extremely useful and versatile device which can be used in a wide range of applications. Its bidirectional I2C interface means that the device can easily be incorporated into automated test systems and its 6-bit digital resolution makes it more accurate than conventional potentiometers. Its operating temperature range and tolerance also make it ideal for use in a variety of high temperature applications, particularly in digital power supplies and battery-powered equipment.
