Microchip Technology MCP4261-103E/SL Digital Potentiometer

The MCP4261-103E/SL is a dual-channel, 10kΩ digital potentiometer designed by Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This digital potentiometer is part of Microchip's MCP42XX series and offers a versatile solution for applications requiring variable resistance adjustments. It is commonly used in applications such as calibration and tuning circuits, programmable filters, and LCD screen adjustments.

Featuring a 7-bit resolution, the MCP4261-103E/SL provides 128 wiper positions, allowing for fine-tuned adjustments. It operates from a 2.7V to 5.5V power supply, making it suitable for both 3V and 5V systems. The device offers a non-volatile memory (EEPROM) to store the wiper position, ensuring the last set position is retained even after power is cycled.

This digital potentiometer comes in a compact 14-pin SOIC (SL) package, which is ideal for space-constrained applications. It also features an SPI interface, which ensures easy communication with most microcontrollers, providing a simple way to integrate into existing designs.

The MCP4261-103E/SL is characterized by its low temperature coefficient and high endurance, making it reliable for use in a wide range of environmental conditions. It is also equipped with a WiperLock™ Technology which allows users to lock the wiper setting, preventing unintended changes to the resistance settings.

Key features of the MCP4261-103E/SL include:

• 10kΩ resistance value
• 128 wiper positions for fine resolution
• Non-volatile memory to retain settings
• Simple SPI serial interface
• Low power consumption
• High reliability and endurance
• WiperLock™ Technology to secure settings
• Operational temperature range from -40°C to +125°C

In summary, the MCP4261-103E/SL digital potentiometer from Microchip Technology is a highly reliable and precise solution for designers looking to add adjustable resistance to their electronic circuits without compromising on space or power consumption.
