AD8402AN100 Classification

Digital Potentiometers ICs

Digital Potentiometers ICs are a new type of CMOS digital and analog mixed signal processing integrated circuit that replaces the traditional mechanical potentiometer (analog potentiometer). It is usually composed of multiple fixed resistors and a movable contact. Its working principle is to control the position of the potentiometer through digital signals, thereby changing the resistance value in the circuit. Digital Potentiometers ICs have the advantages of high precision, good stability, and fast response speed. Before using a digital potentiometer, please select the appropriate potentiometer model and specifications.

FAQ about Digital Potentiometers ICs

  • 1. What is the value of a digital potentiometer?

    The value of a digital potentiometer depends on its wiper position and bit value. The value of a digital potentiometer is usually determined by its tap position. The more taps, the higher the resolution and the finer the value change. For example, an 8-bit digital potentiometer has 256 taps, while a 5-bit digital potentiometer has 32 taps.
    The value of a digital potentiometer can be changed by programming its tap position. For example, when the potentiometer is coded in the middle position, the upper and lower resistance values ​​are equal; at the full scale position, the upper resistance is 0 and the lower resistance is the maximum value; at the 0 position, the lower resistance is 0 and the upper resistance is the maximum value. Specifically, the value range and accuracy of a digital potentiometer depend on its design and bit value. For example, an 8-bit digital potentiometer can provide 256 different resistance values, while a 5-bit digital potentiometer provides 32 different resistance values.

  • 2. What are the components of a digital potentiometer?

    A digital potentiometer mainly consists of two parts: a voltage divider and a controller.
    The voltage divider consists of a series of resistor elements that divide the input voltage according to a certain ratio. Each resistor element is connected to the input pin of the controller. The controller is responsible for reading the control signal and opening or closing the corresponding switch according to the level of the signal, thereby changing the total resistance.

  • 3. How to use digital potentiometers?

    Digital potentiometers are a new type of CMOS digital and analog mixed signal processing integrated circuit that replaces traditional mechanical potentiometers. It is controlled by digital inputs, produces an analog output, and has precise resistance adjustment functions.
    The basic components of digital potentiometers include voltage dividers and controllers. The voltage divider consists of a series of resistor elements that divide the input voltage according to a certain ratio; the controller is responsible for reading the control signal and opening or closing the corresponding switch according to the high or low signal, thereby changing the size of the total resistance.
    When using a digital potentiometer, you first need to make a hardware connection. For example, connect the encoding mode of the EC11 digital potentiometer to a specific pin of the timer. Then, the mode of the encoder is controlled by software to adjust the digital potentiometer. The specific operations include entering the potentiometer mode, adjusting the value, and saving the setting.
