AD5262BRU200 Application Field and Working Principle

Digital potentiometers are an essential part of data acquisition and power monitoring systems, providing two analog outputs which can be adjusted independently from an external control voltage or digital signal. The AD5262BRU200 is a digital potentiometer from Analog Devices that can provide an adjustable voltage up to 2.5V to each output and a 4.5V range for the input control voltage. The AD5262BRU200 comes in a 9-lead PDIP (plastic dual in-line package) and is highly suitable for small-scale applications, such as battery-powered systems, weighing systems, and data communications. The on-chip voltage reference provides high accuracy with a variation of less than 50 ppm/V, while the on-resistor and over-temperature protection ensure reliability and safety.The basic operating principle of the AD5262BRU200 is relatively simple. There are two voltage input lines, one for the control voltage and one for the voltage reference. The control voltage is read by the internal ADC, then converted to a digital code which is compared to the reference voltage. The output voltage is then adjusted to the proper level and kept at a constant by the on-chip digital-to-analog converter and the feedback loop.The AD5262BRU200 has multiple features that can be used to optimize it for the desired application. The user can select between a relative or absolute programming mode, depending on the programming voltage range required. The user can also choose between a high speed or low power operating mode. Additionally, the user can set the device to trigger shutdown at a preset temperature, thus ensuring device reliability and safety in extreme conditions.In conclusion, the AD5262BRU200 is a digital potentiometer from Analog Devices. It is suitable for many small-scale applications such as battery-powered systems, weighing systems, and data communications. Its on-chip voltage reference, on-resistor and over-temperature protection make it highly reliable and safe. Lastly, the user can customize the device with certain features, such as programming mode and operating mode, to make it suitable for their application.
