MCP4461-503E/ML

MCP4461-503E/ML Description

The MCP4461-503E/ML from Microchip Technology is a quad-channel digital potentiometer (digipot) with a 50kΩ resistance and 257-tap resolution, offering precise analog adjustment via an I2C interface. Designed for surface-mount applications, it operates within a 1.8V to 5.5V supply range, making it suitable for low-power and portable devices. The device features WiperLock™ technology, ensuring wiper position retention during power cycles or noise events. With a ±20% tolerance and 150ppm/°C temperature coefficient, it delivers stable performance across industrial temperature ranges. Its 75Ω typical wiper resistance minimizes signal distortion in analog circuits.
