Frequently Asked Questions
What is the end-to-end resistance value of the MCP4261-104E/SL?
The MCP4261-104E/SL has a 100 kΩ end-to-end resistance (the '104' suffix denotes 100 kΩ). It is an 8-bit digital potentiometer providing 256 wiper positions across the 100 kΩ range, enabling fine-grained resistance adjustment for analog signal control applications.
How does the non-volatile memory in MCP4261 benefit embedded control designs?
The MCP4261 stores wiper positions in non-volatile memory, so calibration settings are retained across power cycles without requiring host microcontroller re-initialization. This is critical for 8-bit gain or bias settings in field-deployed sensor nodes, industrial controllers, and medical devices where manual recalibration after power loss is not practical.
For a 14-pin SOIC footprint design, how does MCP4261 compare to single-channel alternatives?
The MCP4261 integrates 2 independent digital potentiometer channels in a single SOIC-14 package, reducing BOM count compared to using 2 separate 8-pin single-channel devices. Each channel offers 256 steps across 100 kΩ, and both share a single SPI bus, saving up to 2 chip-select lines in multi-channel designs.
