X9C103S Digital Potentiometer Board Module

Description

The X9C103S is a digital potentiometer integrated circuit (IC) that allows for precise electronic adjustment of resistance, serving as a replacement for mechanical potentiometers in various electronic applications. It offers a resistance range of 0 to 10kΩ with 100 steps and can be digitally controlled, making it ideal for applications requiring accurate and repeatable resistance settings. It can function as either a 3-terminal potentiometer or a 2-terminal variable resistor.

The potentiometer uses a 3-wire control interface, making it easy to integrate into microcontroller-based systems. It can handle up to ±5V across its end-points, providing a wide voltage range for use in different circuits. The potentiometer’s 100 steps provide a step resolution of approximately 50mV when connected across 5V. Its two ends can be connected to voltages ranging from -5V to +5V, offering flexibility in voltage settings. With the source capability of 4.4mA, the X9C103S is suitable for applications requiring current control. It features a red power LED that indicates when power is applied, simplifying its status monitoring.

The IC features a three-terminal configuration, ensuring easy integration into different electronic circuits. Additionally, it includes non-volatile memory to retain the last resistance setting even after power-off, while its low power consumption makes it suitable for battery-operated devices. The X9C103S Digital Potentiometer is a durable and reliable component with enhanced durability compared to traditional mechanical potentiometers. Some variants of the X9C103S come with a Serial Peripheral Interface (SPI), allowing seamless integration with microcontrollers and digital control systems.
