This IC is Digital Potentiometer 100kΩ 129-Position 2-Channel SPI 14 Pin, TSSOP (MCP4261-502E / ST TSSOP). A digital potentiometer can automatically vary its resistance depending on the given condition. A digital potentiometer acts exactly like a potentiometer whose resistance can be varied by digital communication (like I2C, SPI) instead of rotating the knob directly.
Package Includes:
1 x Digital Potentiometer 100kΩ (MCP4261-502E / ST TSSOP)
