Data Acquisition - Digital Potentiometers

The MCP42010-E/ST digital potentiometer is a monolithic device integrated by Microchip Technology, Inc. It contains two independent non-volatile memory (EEPROM) wiper registers that can store two different values, providing a wide range of resistance-ratio combinations. This device is offered in 8-pin SOIC, 8-pin TSSOP, and 8-pin miniSpace packages.

Application Field

The MCP42010-E/ST can be used in a wide variety of applications including, but not limited to, motor control, LED lighting, servo control, and programming of electrical parameters. The device is ideal for use in automotive, industrial, and portable applications. In addition, the digital potentiometer has excellent temperature performance and low voltage drift characteristics over a wide range of temperatures.

The MCP42010-E/ST is commonly used in the following application areas:

• Precision potentiometer adjustment
• Time-based control
• Temperature and stress compensation
• Remote control
• Dimming/lighting control
• Audio control
• Motor systems
• Power supplies
• Analog front ends

Working Principle

The MCP42010-E/ST digital potentiometer features adjustable resistance that is digitally programmable in an 8-bit programmable register. The resistance values can be set to any value between 0 Ω and 32 kΩ. The device connects to a 3.3 V logic supply and can provide output resistance values with superior linearity and temperature characteristics.

The device contains two sets of 8-bit registers that can each store two values. Each register is programmed to a specific resistance value. These two registers can be used independently to provide two different sets of resistance values or can be combined to produce one combined resistance value. This allows the device to provide versatile and efficient control over changing resistance ratios.

The MCP42010-E/ST digital potentiometer provides two sets of output resistance terminals (A and A\'). The resistance terminals are connected internally and the resistance values of each terminal can be adjusted independently or in combination. Thus, the device can provide fine adjustment and changes in resistance ratios, at a fraction of the cost and space of a standard trimmer potentiometer.

The device features a non-volatile memory (EEPROM) to store resistance values, providing non-volatile wiper settings to survive loss of power. The device features write protection to prevent tampering and accidental setting changes and can be updated at any time.

Conclusion

In conclusion, the MCP42010-E/ST digital potentiometer is a highly versatile, cost effective, and space efficient device that can be used in a variety of application areas. The device offers precise adjustment and control over resistance values, with excellent temperature performance and low voltage drift characteristics. The device also features a non-volatile memory to store resistance settings, ensuring that settings are not lost when power is lost. The MCP42010-E/ST digital potentiometer is an excellent choice for applications where precise adjustment and control over resistance values is desired.
