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. |
