Data Acquisition - Digital Potentiometers - X9428YS16IT1 Application Field and Working Principle

Digital potentiometers are electronic circuits that can be used to accurately adjust the electrical resistance of a circuit. This adjustment can be used to vary the gain of an amplifier, control the brightness of a light-emitting diode (LED) or to adjust the speed of a motor. The X9428YS16IT1 is a 16-bit digital potentiometer with a wide range of applications.

Fields of Application

The X9428YS16IT1 offers a number of advantages when used in automated systems. The chip’s operating temperature range of -40C to 85C allows it to be used in a variety of industrial and automative applications. The digital potentiometer features 8k-bit of on-board non-volatile EEPROM, meaning that the settings remain even when the power is turned off. This makes it suitable for reliable control loops and for applications that require reliable settings.

The 16-bit resolution offers a wide range of adjustment, from 0.0 to 14.3mV to 1.2V depending on the voltage mode. This allows for very precise control, with an accuracy of ±10 mV for the microvolt range and ±120 mV for the higher voltage range. Additionally, the chip features an adjustable wiper, which allows the user to fine-tune the resolution by selecting the appropriate value.

The X9428YS16IT1 also comes with a 1-Wire serial interface, allowing the user to control the digital potentiometer remotely. This is especially useful in applications where a remote control is necessary, such as automation. Finally, the chip features a low power consumption, making it suitable for battery-powered applications.

Working Principle

The X9428YS16IT1 works by changing the resistance value across two terminals. The resistance is changed by adjusting the wiper, which is connected to a wiper control pin on the digital potentiometer. The wiper control pin can take a number of different values depending on the application and the desired resistance value. The wiper can then be adjusted using a voltage input or a digital signal, allowing for precise control.

The digital potentiometer is also able to store a number of settings in the non-volatile memory, allowing the settings to remain unchanged even when the power is removed. This makes the device useful in applications where it is necessary to maintain the same settings. Additionally, the on-board 1-Wire serial interface allows for remote control of the device, making it easy to adjust the settings from a distance.

The X9428YS16IT1 is a versatile and reliable digital potentiometer, offering a wide range of applications. Its low power consumption makes it suitable for battery-powered applications, while its 16-bit resolution and adjustable wiper allow for precise control. Additionally, the device’s non-volatile memory allows for reliable control loops, and its 1-Wire serial interface allows for easy remote control of the device.
