MCP42100-I/SL Description

Short technical summary and product information.

The MCP42100-I/SL from Microchip Technology is a dual-channel digital potentiometer designed for precise resistance control in electronic circuits. It offers 256 discrete tap positions for fine-tuning resistance values, with a nominal resistance of 100 kΩ and a tolerance of ±30%.

 

This device features an industry-standard SPI serial interface, enabling easy integration with microcontrollers and other digital systems. It operates from a single supply voltage ranging from 2.7V to 5.5V, making it suitable for a wide array of applications. The MCP42100-I/SL consumes minimal power, with a maximum supply current of 1 µA in static operation.

 

Designed for surface mounting, the MCP42100-I/SL comes in a 14-SOIC package. It operates within an industrial temperature range of -40°C to +85°C. Key electrical characteristics include ±1 LSB maximum Integral Non-Linearity (INL) and Differential Non-Linearity (DNL), ensuring accurate performance. The linear taper allows for predictable resistance adjustments.
