MCP4017/18/19 are programmable resistor products produced by Microchip Technology Inc., with four resistance values of 5kΩ, 10kΩ, 50kΩ and 100kΩ, 7-bit resolution, low temperature drift and low power consumption.
The MCP4017/18/19 series are 7‑bit single‑ro digital potentiometers with volatile memory, offered in rheostat or potentiometer configurations. They support a simple I²C‑compatible serial interface with read and write commands, brown‑out reset protection, and a mid‑scale power‑on default wiper setting.
The datasheet details electrical characteristics such as a supply voltage range of 2.7 V to 5.5 V, operating temperature from –40 °C to +125 °C (extended), low wiper resistance (~100 Ω typical), and maximum output currents of 25 mA. Package options include SC70‑6 and SC70‑5, and the device offers low‑power operation up to 2 MHz.
