Data Acquisition - Digital Potentiometers have become one of the most important components in the application of electrically controlled systems. The X9313US-3 is a single-channel, programmable digital potentiometer with bidirectional end to end resistance. Being able to provide a resistance range of up to sixteen kilo ohms, and act as both a variable resistor and a digital-to-analog converter, the X9313US-3 can be used in a wide variety of applications.

The X9313US-3 is typically used in two main applications, motor and audio control. With the added features of an integrated wiper for variable resistance, along with a non-volatile memory function to store potentiometer values, the X9313US-3 can be used to control the speed and direction of DC motors, as well as control the gain of standard audio signals.

The working principle of the X9313US-3 is fairly straightforward. As previously mentioned, the X9313US-3 acts as both a variable resistor and DAC. The main role the digital potentiometer acts in this application is that of a variable resistor. In this role, the X9313US-3 is able to change the resistance between its two fixed end points that can span up to 16 kilo Ohms. This is done by controlling the tap point along the resistance range, which is done by the on-chip wiper.

The other main role of the X9313US-3 is that of a DAC. In this role, the digital potentiometer\'s resistance can be digitally changed (programmed) to provide an analog signal output based on the resistance value. This allows for use of the X9313US-3 in applications such as motor and audio signal control. The wiper resistance is set by the input of a digital signal on the DIN signal pin.

The X9313US-3 offers a broad range of features, such as an integrated non-volatile memory, an on-chip wiper for variable resistance control, and a low-distortion output. Combined with its small size and relatively low power dissipation, this makes it an ideal choice for many applications, including motor and audio control. The X9313US-3 digital potentiometer is a versatile and reliable choice for a wide range of applications.
