MCP42050-E/P Description

Short technical summary and product information.

The MCP42050-E/P from Microchip Technology is a versatile dual-channel digital potentiometer designed for a wide range of applications. It offers 256 discrete tap positions for each potentiometer, allowing for fine-grained control. The device features a nominal resistance of 50kΩ with a ±30% tolerance and a linear taper.

 

Communication with the MCP42050-E/P is handled via an industry-standard SPI serial interface, supporting modes 0,0 and 1,1. It operates from a single supply voltage ranging from 2.7V to 5.5V and consumes a low static current of just 1µA maximum. The device is specified for an extended industrial temperature range of -40°C to +125°C.

 

This digital potentiometer is available in a 14-pin PDIP package, suitable for through-hole mounting. It also includes features like a cascade pin for daisy-chaining multiple devices and hardware shutdown functionality on the MCP42XXX series. The wiper position is reset to mid-scale upon power-up or via a hardware reset pin.
