MCP41100-I from Microchip Tech, in a SOIC-8. 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 | CS | input | Chip Select; SPI port chip select pin used to execute a new command after it has been loaded into the shift register, with Schmitt Trigger input. |
| 2 | SCK | input | Serial Clock; SPI port clock pin used to clock-in new register data on rising edge and clock out on falling edge, gated to CS pin, with Schmitt Trigger input. |
| 3 | SI | input | Serial Data Input; SPI port serial data input pin for clocking command and data bytes into the shift register, gated to CS pin, with Schmitt Trigger input. |
| 4 | VSS | power_in | Ground; 0V reference for device and potentiometer circuit. |
| 5 | PA0 | passive | Potentiometer Terminal A Connection; resistor terminal A of potentiometer 0, voltage range 0V to VDD. |
| 6 | PW0 | passive | Wiper Connection For Potentiometer 0; wiper terminal whose voltage varies linearly with 8-bit data register code (00h to FFh). |
| 7 | PB0 | passive | Potentiometer Terminal B Connection; resistor terminal B of potentiometer 0, voltage range 0V to VDD. |
| 8 | VDD | power_in | Power supply; single supply operation 2.7V to 5.5V. |
