X9116WS8Z-2.7 - Data Acquisition - Digital Potentiometers

Digital potentiometers are commonly used as a data acquisition device in engineering and scientific applications. The X9116WS8Z-2.7 is a popular digital potentiometer that is used in many applications, such as motor control, power supplies, sensors, and amplifier/mixer audio. This article will discuss the application field and working principle of this device.

Application Field of X9116WS8Z-2.7

The X9116WS8Z-2.7 is a 3-terminal, 256-position digital potentiometer. It is a non-volatile, two-wire controlled digital potentiometer. It is commonly used in a wide range of industrial, consumer and medical applications that require the substitution of mechanical or optical potentiometers.

In the motor control and power supplies fields, the X9116WS8Z-2.7 is used to control the speed and torque of an AC or DC motor. It can also be used to change the supply voltage of an electronic device. In the sensors area, its low temperature drift and fast response time make it an ideal solution for pressure, temperature and humidity sensing.

In audio amplifier/mixer applications, X9116WS8Z-2.7 is used to adjust the audio gain and control the balance. Its low noise characteristics make it suitable for low distortion and wide frequency range audio systems.

Working Principle of X9116WS8Z-2.7

The X9116WS8Z-2.7 device is a resistive network consisting of a series of resistors tied to a common contact. The device is controlled by two external signals, a clock signal and a data signal, which are used to set the device to a specific resistance or wiper setting. The clock and data inputs send out a series of digital bits that determine which resistor in the network is selected and connected to the common contact.

The actual resistance value is determined by the number of bits received and the resistance values of the resistor network. The X9116WS8Z-2.7 is designed to be used in a wide range of voltage supplies from 2.7V to 5.5V. Its ESD rating is up to 8kV HBM and it has a temperature coefficient of resistance (TCR) from 1 ppm/degreeC to 50 ppm/degreeC.

Conclusion

The X9116WS8Z-2.7 is a popular digital potentiometer that is used in many applications, such as motor control, power supplies, sensors, and amplifier/mixer audio. Its non-volatile memory, wide range of voltage supplies, ESD rating and temperature coefficient of resistance make it an ideal solution for data acquisition and control in these fields.
