X9116WM8I-2.7T1 application field and working principle

The X9116WM8I-2.7T1 is a high-performance digital potentiometer integrated into a 9-pin DIP package with multi-bit nonlinear configuration word. This integrated circuit enables the user to generate a signal whose magnitude varies in accordance with an external signal, such as a temperature variation. As a programmable voltage divider, such as a digital potentiometer, the X9116WM8I-2.7T1 may be used in various applications, such as data acquisition, signal conditioning, control systems, instrumentation, and even in the audio market. Hence, the X9116WM8I-2.7T1 is mainly used in data acquisition applications.The X9116WM8I-2.7T1 consists of an 8-bit + dummy bit configuration word, allowing to adjust the wiper voltage outputs in 256 increments. An internal switched capacitor DAC architecture is used to achieve a total voltage range of 62.5mV, with a step resolution of 0.25mV. This integrated circuit has a power-down feature with 0.06% typical step nonlinearity and provides an output resistance that ranges from 5KΩ to 10KΩ.The X9116WM8I-2.7T1 features a control word shift register, an On/Off switch, and a power-down logic (shutdown) section. In order to program the X9116WM8I-2.7T1 digital potentiometer, the user can either load a digital word into the control word shift register or change the impedance of the external resistor, which will determine the output voltage level. The On/Off switch feature allows the user to turn the device off when it is not in use. The two power-down logic lines enable the user to power down the device while still maintaining the accuracy of the output voltage.Using the X9116WM8I-2.7T1 digital potentiometer, is possible to measure the magnitude of an electrical signal and adjust the output voltage level accordingly. This is especially useful when the input signal is variable, such as temperature variations. The X9116WM8I-2.7T1 offers a solution in these applications as it requires a minimum number of external components and provides a low-cost solution.The X9116WM8I-2.7T1 digital potentiometer is a versatile solution for data acquisition and signal conditioning applications. Its wide range of adjustment options, low power consumption, high accuracy, and fast switching time are beneficial in data acquisition, signal conditioning, and control applications, among others. Additionally, its 9-pin DIP package ensures that the X9116WM8I-2.7T1 digital potentiometer is easy to integrate into any existing PCB boards.
