The Microchip Technology MCP4451-103E/ST is a versatile quad digital potentiometer designed for various control applications. It offers a 10k Ohm resistance value with a linear taper and 8-bit resolution, providing 257 taps for precise adjustments.
This device supports an I2C serial interface, allowing for high-speed read and write operations to the wiper. It operates within a wide voltage range of 1.8V to 5.5V, making it suitable for diverse system designs. The MCP4451-103E/ST also includes features like brown-out reset protection and high-voltage tolerant digital inputs.
Packaged in a 20-TSSOP, this surface-mount component is designed for efficient integration into electronic circuits. Its operating temperature range is -40°C to 125°C, ensuring reliable performance in demanding environments. The typical wiper resistance is 75 Ohms, and it has a temperature coefficient of 15 ppm/°C (ratiometric).
This digital potentiometer is ideal for applications requiring adjustable voltage dividers, gain control, or filter tuning where digital control is preferred over mechanical potentiometers.
