MCP42010-E/ST

Digital Potentiometers Overview

The MCP42010-E/ST is a dual-channel digital potentiometer from Microchip Technology, featuring two independent 10 kΩ resistive networks with 256 linear tap positions. It operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via an industry-standard SPI serial interface supporting modes 0,0 and 1,1. The device includes hardware shutdown and reset pins for power management and state control. Packaged in a 14-pin SOIC (T) format, it is specified for operation across the extended industrial temperature range of -40°C to +125°C.

Digital Potentiometers Feature Summary

• Dual-channel architecture with 256-position linear wiper control
• SPI serial interface with daisy-chaining capability via SO pin
• Hardware Shutdown (SHDN) and Reset (RS) pins for power and state management
• Extended temperature range specification (-40°C to +125°C)

Digital Potentiometers Applications

• Replacing mechanical potentiometers in volume control circuits
• Programmable gain amplifier configurations
• Voltage reference adjustment systems

Digital Potentiometers Procurement Notes

Verify that the ordering suffix '/ST' corresponds to the 14-pin SOIC package variant. Confirm the 'E' designation indicates the extended temperature grade (-40°C to +125°C). Ensure the specific revision of the datasheet DS11195C matches the production lot requirements for electrical characteristics.

Digital Potentiometers Selection Notes

Select this component when dual independent channels are required within a single package. The 10 kΩ resistance value suits moderate current applications. Verify that the system logic levels are compatible with the SPI interface inputs. Consider the SOIC package dimensions against available PCB real estate constraints.

Digital Potentiometers Part Context

This part belongs to the MCP42XXX family of dual digital potentiometers. It shares core functionality with variants like the MCP42010-I/P but differs in package type (SOIC vs PDIP) and temperature rating (Extended vs Industrial). The 'E' suffix specifically denotes the extended temperature capability compared to standard industrial grades.

Digital Potentiometers Replacement Considerations

Direct substitutes include other MCP42010 variants such as MCP42010-I/SL or MCP42010-E/SN, provided the package footprint and temperature specifications align with the design requirements.
