MCP4011-502E
Microchip Tech · Digital Potentiometers · MSOP-8
MCP4011-502E 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, operating from 1.8V to 5.5V relative to VSS, with a decoupling capacitor on VDD to VSS recommended for maximum performance. |
| 2 | VSS | power_in | Ground reference pin for the device. |
| 3 | A | passive | Potentiometer terminal A, the fixed connection to the 0x3F terminal of the digital potentiometer; the voltage must be between VSS and VDD and it supports both positive and negative current. |
| 4 | W | passive | Potentiometer wiper terminal, the adjustable terminal of the digital potentiometer; the voltage must be between VSS and VDD and it supports both positive and negative current. |
| 5 | CS | input | Chip select input; forcing CS to VIL enables serial commands, forcing it to VIHH enables high-voltage serial commands, and it has an internal pull-up resistor. |
| 6 | B | passive | Potentiometer terminal B, the fixed connection to the 0x00 terminal of the digital potentiometer; the voltage must be between VSS and VDD and it supports both positive and negative current. |
| 7 | NC | unconnected | No connection. |
| 8 | U/D | input | Increment/decrement input that moves the wiper one step toward terminal A on an increment and one step toward terminal B on a decrement. |
