The X9C503ST1 is a digital potentiometer manufactured by Xicor. It has a single non-volatile memory register to store the wiper setting, which is accessible via a serial data format. It is programmed with a byte or a byte character corresponding to the desired wiper setting. The X9C503ST1 is a 5-position version of Xicor\'s port-sensitive devices, meaning that the control and data inputs are only active during a specific interval.

The X9C503ST1 is designed for use in a wide range of applications, including data acquisition and signal processing, motor control, and power supply management. It provides a simple, effective method of remotely controlling the voltage or resistance levels of multiple devices. For example, it can be used to adjust the gain of an amplifier, or control the speed of a motor. It is also useful for setting the voltage output of a DC-DC converter, or for dynamically setting the reference voltage of an adjustable current source.

The X9C503ST1 works by transferring data from the controlling computer (or other controlling device) to the digital potentiometer via a serial data interface. This data is converted into a digital signal, which is then used to adjust the resistance level of the component. The component is then able to output a voltage or current that is proportional to the change in the resistance value.

The X9C503ST1 has a high accuracy and repeatability due to its wiper technology, which is based on EEPROM (electronically erasable programmable read-only memory) to store the current resistance value. The component also features an input register, a latch register, and a shift/status register to provide a powerful and flexible interface to external systems.

The X9C503ST1 is available in a variety of package types, including plastic DIP, surface mount SOIC, and SMT leadless packages. The X9C503ST1 is a cost-effective solution for applications requiring a high accuracy programmable digital potentiometer.
