MCP4011T-503E from Microchip Tech, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Positive power supply input, relative to VSS, ranging from 1.8V to 5.5V, with a decoupling capacitor to VSS recommended. |
| 2 | VSS | power_in | Device ground reference. |
| 3 | A | passive | Potentiometer terminal A, the fixed connection to the 0x3F end of the resistor array; it has no polarity, supports positive and negative current, and must stay between VSS and VDD. |
| 4 | W | passive | Potentiometer wiper terminal, the adjustable terminal; it has no polarity, supports positive and negative current, and must stay between VSS and VDD. |
| 5 | CS | input | TTL chip select input with an internal pull-up; VIL enables serial commands, VIHH enables high-voltage serial commands compatible with MCP402X, and a floating pin ignores the U/D pin. |
| 6 | B | passive | Potentiometer terminal B, the fixed connection to the 0x00 end of the resistor array; it has no polarity, supports positive and negative current, and must stay between VSS and VDD. |
| 7 | NC | unconnected | No connection. |
| 8 | U/D | input | TTL increment/decrement input; an increment moves the wiper one step toward terminal A and a decrement moves it one step toward terminal B. |
