The X9428WV14Z-2.7 is a digitally controlled prime analog potentiometer product that belongs to a class of data acquisitions devices referred to as digital potentiometers. These devices work by utilizing two external terminals to establish a reference point, known as the wiper terminal, from the output of the device. From this point, the wiper terminal can then be varied according to the amount of voltage applied to the device.The many application fields that the X9428WV14Z-2.7 is capable of addressing vary from voltage ramps and volume controls, to instrumentation amplifiers, to computer peripherals such as game controllers and keyboards. In some applications, this type of analog potentiometer can even be used for LED displays and LEDs to provide variable brightness and other features.The basic working principle of the X9428WV14Z-2.7 is based upon the fact that it is composed of three terminals which are connected together. Two of these are the external terminals that establish the set point, and the third is the wiper terminal. Using voltage signals, the wiper terminal can then be varied according to the input applied to the device.The device uses a programmable memory to control the movement of the wiper. This memory can either be configured to use a software or hardware port to provide either direct or indirect control interface, or it can also be used to allow for automatic adjustments of the wiper terminal.A feature of the device that makes it very attractive in the field of data acquisition is its high accuracy. This is due to its four-bit linear technology and multiplexed bus architecture. This feature allows for a high level of resolution. The maximum resolution achieved by the X9428WV14Z-2.7 is a full 16-bit resolution, with the ability to adjust the voltage in increments of one-tenth a volt.In summary, the X9428WV14Z-2.7 is a member of the digital potentiometer family and can be used for a number of different applications. It provides users with a high level of accuracy and resolution, as well as the ability to program the memory for either direct or indirect control interface and allow for automatic adjustments. With such high accuracy and flexibility, the X9428WV14Z-2.7 is definitely a great option for data acquisition and control.
