X9410WP24-2.7

Data Acquisition - Digital Potentiometers

The X9410WP24-2.7 is a digital potentiometer based on input and output technologies. It is designed for precision applications in the areas of data acquisition and control. It is used for controlling voltage and current levels, for example in automotive applications.

Application Field

The X9410WP24-2.7 is a digital potentiometer that is routinely employed to program the power output of a motor drive system. It is also used to control the voltage drop of a resistor in an electronic circuit and to adjust the charging or discharging rate of a battery. It is also completely suitable for use in fuel cell and hybrid vehicle power control systems.

The digital potentiometer is applicable for use in precision avionics and aerospace control systems, for the manipulation of optical fiber communications networks, for managing the altitude and attitude control of hydroponic systems, and for gauging and controlling pressure in hydraulic systems.

Working Principle

The X9410WP24-2.7 operates on the premise that a potential divider is subjected to an input voltage. This causes the overall potential divider to be pulled down, which in turn causes the current to be diverted through the output control pins. The analog signals at these pins, in turn, manipulate the voltage or current output of the system, based on the position of the potentiometer.

The device comes with a 4-bit non-volatile memory, allowing the connected system to save the potentiometer’s dial reach, or current position on the sliding arm. It carries an analog block functionality and has an operating frequency of up to 50kHz. The device draws a maximum operating current of 2mA. It can be programmed and operated through the general-purpose I2C interface, with a 100kHz clock signal.

The X9410WP24-2.7 is comprised of a main digital potentiometer and an associated voltage divider, which form the basis for the control of both voltage and current levels. It contains its own control logic, including an 8-bit ADC interface and a 4-bit DAC output pin. Programmable shaft delay time and clocking frequency are also available.

Conclusion

Digital potentiometers like the X9410WP24-2.7 are highly effective devices for precise control in a variety of applications. They are well suited for motor drives, optical fiber networks, avionics and aerospace systems, hydroponics and Automotive applications. The device operates on the basic principle of diversifying current by subjecting a potential divider to an input voltage, and carries useful features such as a 4-bit memory and I2C programming/operation interface.
