MCP4018T-502E from Microchip Tech, in a SC-70-6(SOT-363). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive power supply input, 1.8 V to 5.5 V (analog characteristics specified from 2.7 V to 5.5 V). A decoupling capacitor to VSS is recommended for best performance.
2 VSS power_in Device ground reference (0 V). Also serves as the internal connection for potentiometer terminal B on the MCP4018.
3 SCL input I2C serial clock input. Schmitt-trigger input with open-drain output; requires an external pull-up resistor. Tolerates up to 12.5 V with respect to VSS (see Absolute Maximum Ratings).
4 SDA bidirectional I2C serial data line. Schmitt-trigger input with open-drain output; requires an external pull-up resistor. Tolerates up to 12.5 V with respect to VSS.
5 W passive Potentiometer wiper terminal (analog). Adjustable tap of the resistor network; voltage must lie between VSS and VDD, maximum terminal current 2.5 mA. No polarity restriction relative to terminal A.
6 A passive Potentiometer terminal A (analog), fixed connection to the full-scale (0x7F) tap of the resistor network. Voltage must lie between VSS and VDD; maximum terminal current 2.5 mA. Terminal B is internally tied to VSS on the MCP4018.
