The MCP42050-I/ST from Microchip Technology is a 256-position, dual-channel digital potentiometer with a nominal resistance of 50 kΩ. It utilizes an industry-standard SPI serial interface for control, supporting modes 0,0 and 1,1. This device is designed for single-supply operation, with a voltage range of 2.7V to 5.5V.
Key electrical characteristics include a ±30% resistance tolerance and a typical temperature coefficient of 800ppm/°C. The device consumes a maximum of 1 µA in static operation and features ±1 LSB maximum INL & DNL. It also includes a hardware shutdown pin for power savings and a reset pin to return the wiper to mid-scale.
Packaged in a 14-TSSOP, the MCP42050-I/ST is designed for surface mount applications. Its operating temperature range is -40°C to +85°C, making it suitable for industrial environments. The volatile memory type allows for wiper register changes during shutdown mode.
This digital potentiometer is ideal for applications requiring adjustable voltage dividers, gain control, or filter tuning where precise digital control is needed. Its dual-channel configuration and SPI interface facilitate integration into various embedded systems.
