Data Acquisition - Digital Potentiometers

The MCP4452-503E/ST is a digital potentiometer with a resolution of 50K, providing general purpose and digitally controlled variable resistance for applications that require adjustable resistance from 0 to 5KΩ. This variable resistive element, combined with the MCP4452-503E/ST’s versatility and reliability makes it suitable for a wide range of applications, such as adjusting gain, level setting and control of current, voltage, noise and power.

Working Principle

MCP4452-503E/ST operates on a resistive-bridge system, wherein the resistance of a potentiometer is determined by the ratio of two fixed resistors, one a wiper and the other a reference resistor (RREF). In this system, the RREF resistor is usually set to 5KΩ. As the wiper is moved, the resistance of the potentiometer changes accordingly. The MCP4452-503E/ST’s resolution of 50K gives the user a wide range of resistance adjustments, from 0K to 5KΩ, with a resolution of 0.1Ω.

When the MCP4452-503E/ST is connecting to the power supply, it produces an output voltage proportional to its resistance setting. This output voltage can then be used to control various dials, buttons, or other adjustment mechanisms in the system. To further facilitate user control, the MCP4452-503E/ST features an onboard I2C serial bus interface, allowing it to be easily integrated into existing systems.
