Microchip Technology MCP4352-502E/ST Digital Potentiometer

The MCP4352-502E/ST is a high-performance digital potentiometer designed by Microchip Technology, a leader in microcontroller, mixed-signal, analog, and Flash-IP solutions. This digital potentiometer is part of the MCP43XX series and offers a robust feature set that makes it suitable for a wide range of applications including calibration, adjustable power supplies, and signal conditioning.

This particular model comes in a TSSOP-14 package and is designed to operate over a wide temperature range, making it reliable for use in industrial and automotive environments. The MCP4352-502E/ST features dual, 7-bit (129 wiper steps) potentiometers, and each potentiometer's wiper position can be individually controlled through an I2C™Compatible interface, which allows for easy integration into existing systems.

The resistance value of the MCP4352-502E/ST is 5 kΩ, which provides a good balance between resolution and range for various applications. The device also includes non-volatile memory to retain the wiper position through power cycles, ensuring consistent performance and reducing the need for recalibration.

Additional features of the MCP4352-502E/ST include:

• Multiple wiper lock technology to protect wiper settings from accidental changes
• Low tempco over wiper for stable operation
• Wide operating voltage range of 2.7V to 5.5V
• High bandwidth (-3 dB) of 2 MHz typical for precise control
• Extended temperature range of -40°C to +125°C

The MCP4352-502E/ST's digital interface provides a programmable solution for setting and adjusting resistance values, which is more flexible and reliable than traditional mechanical potentiometers. Its precision and digital control make it an excellent choice for automated adjustments where accuracy and stability are critical.

Whether you're designing consumer electronics, automotive systems, or sophisticated industrial equipment, the MCP4352-502E/ST from Microchip Technology offers a versatile and durable solution for your digital potentiometer needs.
