The MCP4251-503E/ML from Microchip Technology is a dual-channel digital potentiometer IC designed for various control applications. It offers a 50k Ohm resistance with a linear taper and 257 steps, providing precise adjustment capabilities.
This device utilizes an SPI serial interface for high-speed read and write operations to its wiper registers. It supports a wide operating voltage range from 1.8V to 5.5V and operates across an extended temperature range of -40°C to +125°C. The typical wiper resistance is 75 Ohms, and it features a typical temperature coefficient of 15 ppm/°C for potentiometer configuration.
Packaged in a 16-QFN (4x4) with an exposed pad, the MCP4251-503E/ML is designed for surface mounting. Its configuration options include potentiometer and rheostat pinouts, with a network terminal disconnect feature available via a shutdown pin or terminal control register. The device also includes brown-out reset protection and internal weak pull-up resistors on digital inputs.
