Microchip Technology MCP4017T-502E/LT

Description
The MCP4017/18/19 are 7-bit single I²C™ digital potentiometers with volatile memory. They offer both potentiometer and rheostat configurations, providing a wide range of applications. The devices feature a resistor network resolution of 127 resistors (128 steps), allowing for precise control of resistance. The RAB resistances are available in 5 kΩ, 10 kΩ, 50 kΩ, or 100 kΩ, and the wiper resistance is typically 1000 Ω.
