Data Acquisition - Digital Potentiometers

Digital potentiometers are electronic devices used in various data acquisition circuits, often referred to as "pots". They provide adjustable resistance over a wide range of values, which makes them incredibly useful for calibrating circuit components or creating adjustable voltage divider circuits. The DS1869-50+ is an example of a digital potentiometer, and this article will discuss its application field and working principle.The DS1869-50+ is an analog device that can vary resistance over a range of 0-50 Ohms. It is used in data acquisition circuits, often to adjust circuit elements such as potentiometers and variable resistors. It has an internal switching network that allows it to be set to any resistance level over the 0-50 Ohms range with either digital or analog control. Additionally, it can also self-adjust its resistance according to an external voltage applied to its inputs.The DS1869-50+ is primarily used in applications where an adjustable resistor is needed, such as measuring strain gauges, temperature sensors, and force transducers. It can also be used to adjust the gain of operational amplifiers, create adjustable voltage dividers, or tune feedback circuits.The DS1869-50+ is typically interfaced with microcontrollers or programmable logic devices through a two-wire or three-wire bus. This bus interface allows the device to be programmed and configured remotely, without the need for manual adjustment. The DS1869-50+ has two digital inputs, as well as an analog input, which can be used to control its resistance value. The digital inputs are used to select the resistance value, which is then adjusted using the analog input.The working principle of the DS1869-50+ is based on the use of an internal oscillator that controls the switching of a series of transistors. The transistors are connected in parallel, each one switching on and off at different frequencies to create the desired resistance level. By controlling the frequency of the oscillator, the transistors can be switched on and off in such a way that the resistance is adjusted to the desired value.The DS1869-50+ is a versatile device that can be used in a wide range of data acquisition applications. Its ease of use and built-in features make it an ideal choice for those in need of an adjustable resistor. Furthermore, its ability to be operated and programmed remotely through a bus interface makes it an attractive option for those looking for a digital potentiometer.
