Data Acquisition - Digital Potentiometers

Digital potentiometers are electronic components used to control the electrical potential of circuit components such as transistors, resistors and capacitors. The digital potentiometer AD5161BRM5 is one of the most popular digital potentiometers today, due to its flexible application possibilities and reliable working principle.The AD5161BRM5 is a digitally controlled digital-to-analog converter. It is a dual, non-volatile, resistor-string device that contains an array of 64 unit-length resistors. With this device, it is possible to maintain a custom profile of resistances across two different channels.The AD5161BRM5 provides two channels of independent resistor positions, each of which features a 64-step potentiometer consisting of 128 taps. The center of the resistor string is connected to the external reference, or \'Analog backplane\'. This makes it possible to configure the AD5161BRM5 to create a linear or non-linear voltage divider.The AD5161BRM5 can be used to construct various types of transducers such as voltage dividers, voltage-to-frequency converters, current-to-voltage converters and voltage-to-current converters. It can be used in many different applications, such as industrial automation, data acquisition, display control, audio equalizers and many more.Thanks to its non-volatile memory, the AD5161BRM5 can be used in applications that require the control of position even in the event of power interruption. Combined with its low power consumption, this feature makes the device suitable for battery powered systems.The device works by receiving a digital input from a microcontroller and then converting it into an analog signal. The digital input can be a number from 0 to 255 and each value corresponds to a different resistance in the resistor string. The output of the device is tied to the voltage or current of the backplane, so that when the input signal changes, the output voltage or current changes accordingly.The AD5161BRM5 is a versatile and reliable digital potentiometer that can be used for a multitude of applications. Thanks to its non-volatile memory, it is particularly well-suited for controlling the position of voltage dividers, current-to-voltage and voltage-to-current converters, and transducers, as well as being used in industrial automation and data acquisition systems.
