The Microchip Technology MCP4142-103E/MS is a single-channel digital potentiometer with a nominal resistance of 10kΩ. It offers 129 discrete steps for precise resistance control.
This device utilizes an SPI serial interface for communication, supporting high-speed read and write operations to its wiper registers. It features non-volatile memory for automatic recall of saved wiper settings and WiperLock Technology for securing calibration settings. The operating voltage range is from 1.8V to 5.5V, with specified characteristics from 2.7V to 5.5V.
Designed for surface mount applications, the MCP4142-103E/MS comes in an 8-MSOP package. It operates across an extended temperature range of -40°C to +125°C, making it suitable for various environmental conditions. Key electrical features include a low wiper resistance of 75Ω typical and a linear taper.
Additional features include brown-out reset protection, high-voltage tolerant digital inputs up to 12.5V, and support for split rail applications. The device also includes a terminal disconnect feature via a shutdown pin and a write protect feature controlled by a pin or configuration bit.
