Data Acquisition - Digital Potentiometers

Digital potentiometers (also known as digPot) are a class of electrical components that vary the resistance in a similar way to traditionalanalog potentiometers. DigPot units are incorporated within a circuit to provide a variable resistance that can be used to control various parameters. The main advantages of using a digPot over a standard one is that the resistance can be changed electronically rather than by changing the physical position of a wiper, aswell as providing a much wider range of resistance values. The AD5243BRMZ50-RL7 is a precision digPot from Analog Devices, designed for a variety of different applications.

Application Field of AD5243BRMZ50-RL7

The AD5243BRMZ50-RL7 is designed for use in a multitude of different applications. Such applications include:

• Software-controlled volume and gain adjustments in audio/video systems.
• Load balancing in power management systems.
• Automatic gain control in medical instrumentation.
• Tuning radio frequency (RF) communication systems.
• Calibration and trim, including user-adjustable controls.

The AD5243BRMZ50-RL7 can also be used in digital-to-analog (D/A) conversion and digital filter design functions.

Working Principle of AD5243BRMZ50-RL7

The working principle of the AD5243BRMZ50-RL7 is based around the use of a field-programmable resistor. This field-programmable resistor (FPR) is designed to switch between a high and low impedance state depending on a predetermined control voltage. The control voltage that is used to switch the FPR is adjustable so that the wiper resistance can be set by varying the control voltage. The position of the wiper is digitally controlled and a variety of different power supplies can be used to enable the correct voltage levels for operation. The temperature coefficient of the resistor is also adjustable and can be set to a variety of different values. This is particularly important in applications that require a stable resistance over a wide range of temperatures.
