The AD5203ARUZ100-REEL is a digital potentiometer that features an adjustable variable resistor offering controlled resistance variations with 256 discrete parts. This digital potentiometer makes it easy to develop adjustable variable resistor systems that use voltage dividers and fixed resistors to achieve variable resistance. It is a dual 16-bit digitally programmable resistor in 5-lead packages and is designed for high speed and low power applications.

The AD5203ARUZ100-REEL is ideally suited for data acquisition applications where the user requires a variable resistance. These applications include adjustment of bridge circuits and potmeters in audio systems, controlled AC outlets, stepper motor speed control, low frequency signal processing, and frequency synthesizer systems. As the AD5203ARUZ100-REEL is adjustable over a wide range of 256 discrete steps, it makes for fast and easy adjustment of resistance in a variety of applications.

The AD5203ARUZ100-REEL\'s working principle is simple. The digital potentiometer has two switch networks, which are connected in series in a voltage divider bridge. These switches provide a range of resistance between two terminals, on the opposite edges of each switch. The two switch networks are connected such that the sum of the resistors in the two switch networks is always equal to the common resistive value of the digital potentiometer.

When a voltage is applied to the digital potentiometer, the two switch networks are powered. Depending on the voltage level, the switches will then alter the resistance of the digital potentiometer in discrete steps of 256 possible combinations, from a minimum resistance of 0 ohms to a maximum resistance of 255 ohms. By varying the voltage the user can obtain the desired resistance for a given application.

The AD5203ARUZ100-REEL digital potentiometer is also very low power, with a supply current of 0.07 µA. This allows it to safely and efficiently control the resistance of the digital potentiometer in applications where a low voltage, low power, and low current are required, such as on portable devices. The digital potentiometer features a temperature sensor which can be used to adjust the resistance based on the ambient temperature.

The AD5203ARUZ100-REEL digital potentiometer is extremely versatile and can be used in a wide range of applications. It can be easily programmed and controlled with a variety of digital logic levels, making it ideal for use in systems with multiple digital logic levels. This digital potentiometer is also very tolerant to sudden changes in temperature, meaning that it can be used in harsh environmental conditions.

In summary, the AD5203ARUZ100-REEL is an extremely versatile digital potentiometer capable of providing adjustable variable resistors in a wide range of applications where a low voltage, low power, and low current are required. It is adjustable over a wide range of 256 discrete steps, making it easy to adjust resistance in a variety of applications, and it is also very low power and tolerant to sudden changes in temperature.
