Microchip Tech · Digital Potentiometers · SOIC-8
MCP4152-502E from Microchip Tech, in a SOIC-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 | CS | input | Serial interface chip select input (high-voltage tolerant with Schmitt trigger); forcing CS to VIL enables serial commands and forcing it to VIHH enables high-voltage serial commands. |
| 2 | SCK | input | SPI serial clock input (high-voltage tolerant with Schmitt trigger), with the internal weak pull-up on digital inputs. |
| 3 | SDI | input | Serial data input connected to the host controller's SDO pin (high-voltage tolerant with Schmitt trigger), with the internal weak pull-up on digital inputs. |
| 4 | VSS | power_in | Device ground reference; the voltage on the potentiometer terminals must be between VSS and VDD. |
| 5 | P0W | passive | Potentiometer 0 wiper terminal, which can carry positive or negative current and must stay between VSS and VDD. |
| 6 | P0B | passive | Potentiometer 0 terminal B, fixed to the zero-scale wiper value (0x00), which can carry positive or negative current and must stay between VSS and VDD. |
| 7 | SDO | output | Serial data output connected to the host controller's SDI pin, used to read the digital potentiometer registers or monitor the command error bit. |
| 8 | VDD | power_in | Positive power supply input relative to VSS; the electrical performance may not meet the data sheet specifications while VDD is below Vmin (2.7V). |
