MCP42100-I/P Description

Short technical summary and product information.

The MCP42100-I/P from Microchip Technology is a dual-channel, 256-position digital potentiometer. It offers a nominal resistance of 100kΩ with a linear taper and ±30% tolerance. This device utilizes an industry-standard SPI serial interface for control, supporting modes 0,0 and 1,1.

 

Designed for flexibility, the MCP42100-I/P operates from a single 2.7V to 5.5V supply and is specified for an industrial temperature range of -40°C to +85°C. It consumes a maximum of 1µA in static operation, making it suitable for low-power applications. The device also includes features like a hardware shutdown pin for power savings and daisy-chaining capability for multiple devices.

 

Packaged in a 14-pin PDIP, the MCP42100-I/P is designed for through-hole mounting. Its ±1 LSB maximum INL & DNL ensures good linearity. The wiper position is reset to mid-scale upon power-up, and a hardware reset pin is also available.
