MCP42010-E/SL

Digital Potentiometers Overview

The MCP42010-E/SL is a dual-channel digital potentiometer manufactured by Microchip Technology. It features two independent 10 kΩ resistive elements, each with 256 linear tap positions controlled via an SPI serial interface. The device operates on a single supply voltage ranging from 2.7V to 5.5V and consumes less than 1 µA in static mode. It includes hardware shutdown and reset pins for power management and state control. The component is housed in a 14-pin SOIC package and supports industrial temperature ranges.

Digital Potentiometers Feature Summary

• Dual-channel architecture with 256 linear taps per potentiometer
• SPI serial interface supporting Mode 0,0 and Mode 1,1
• Hardware Shutdown (SHDN) and Reset (RS) pins for power and state control
• Low power consumption with <1 µA static current

Digital Potentiometers Applications

• Replacing mechanical potentiometers in volume control circuits
• Adjustable gain settings in signal conditioning amplifiers
• Voltage reference trimming in measurement systems

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and temperature grade. Ensure the required resistance value matches the '010' designation (10 kΩ). Confirm that the SOIC-14 package dimensions align with the target PCB footprint before procurement.

Digital Potentiometers Selection Notes

Select this component when dual-channel digital adjustment is required within a single package. The 10 kΩ nominal resistance is suitable for moderate impedance applications. Verify that the system voltage falls within the 2.7V to 5.5V range. Consider the ±1 LSB INL/DNL specification if high linearity is critical for the application.

Digital Potentiometers Part Context

This part belongs to the MCP42XXX family of dual digital potentiometers. It shares the same core functionality as the MCP42050 and MCP42100, differing primarily in the nominal resistance value of the internal resistor arrays. The 'E' suffix typically denotes the extended temperature grade, while 'SL' indicates the SOIC package.

Digital Potentiometers Replacement Considerations

Direct functional substitutes include the MCP42050-E/SL (50 kΩ) and MCP42100-E/SL (100 kΩ), provided the resistance tolerance allows for the change. Single-channel alternatives like the MCP41XXX series require two separate packages.
