Data Acquisition - Digital Potentiometers

X9418YS24IZ-2.7, an integrated digital potentiometer family, is designed to provide an excellent solution to replace traditional mechanical potentiometers in data acquisition and transducer control applications. With features of an inherently low drift, they are becoming increasingly popular in portable test, medical, and industrial applications.

Application Field

The X9418YS24IZ-2.7 features a low-voltage operation, integrated memory, and unmatched stability, making it an ideal choice for applications where the replacement of mechanical potentiometers is desired. These applications include transducer control and data acquisition, as well as parameter control of a variety of industrial processes. With an increased resolution and accuracy, these devices are also an ideal choice for a variety of medical, aerospace, and automotive applications.

Working Principle

The X9418YS24IZ-2.7 is a digital potentiometer family of devices constructed with an array of binary addressing pins and conductive layers, allowing for an increase in precision compared to conventional electromechanical potentiometers. The device is designed with an array of resistors with high-resolution metal-oxide-semiconductor (MOS) switches that can be addressed to produce accurate resistor settings, according to programming commands. This data is then stored in chip memory, so that the device can be preset to quickly restore the resistor settings upon power-up. The device is also equipped with an end-of-travel limit switch, so that precise resistor settings can be ensured even when the device goes through an extended cycle of usage.

In addition, the X9418YS24IZ-2.7 offers a unique feature of a temperature compensation circuit. This temperature compensation circuit is designed to adjust the resistance settings according to ambient temperature, operating off the same ever-stable power source as the resistor itself. The device also features convenient wiper sensing points, so that the application can read the actual wiper resistance values and compare it with the set values, in order to maintain precise resistance settings.

The X9418YS24IZ-2.7 digital potentiometers family is known for its high resolution, low-voltage performance, and low-current operation, making it an ideal choice for data acquisition and transducer control applications.
