MCP4632-104E from Microchip Tech, in a MSOP-10. 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 | HVC/A0 | input | High Voltage Command / Address 0 input is latched at POR/BOR as the A0 address bit, and it is a high-voltage tolerant Schmitt-trigger input (digital inputs tolerate up to 12.5V). |
| 2 | SCL | input | I2C serial clock input, connected to the host controller SCL; the device is a slave and accepts only external clock signals, with a high-voltage tolerant Schmitt-trigger input. |
| 3 | SDA | bidirectional | I2C serial data I/O, implemented as an open-drain N-channel driver, with a high-voltage tolerant Schmitt-trigger input. |
| 4 | VSS | power_in | Ground reference for the device; all terminal voltages are specified relative to this pin. |
| 5 | P1B | passive | Potentiometer 1 terminal B is the fixed connection to the zero-scale wiper value (0x00), has no polarity, supports both positive and negative current, and must be held between VSS and VDD. |
| 6 | P1W | passive | Potentiometer 1 wiper terminal is the adjustable terminal, has no polarity, supports both positive and negative current, and must be held between VSS and VDD. |
| 7 | P0W | passive | Potentiometer 0 wiper terminal is the adjustable terminal, has no polarity, supports both positive and negative current, and must be held between VSS and VDD. |
| 8 | P0B | passive | Potentiometer 0 terminal B is the fixed connection to the zero-scale wiper value (0x00), has no polarity, supports both positive and negative current, and must be held between VSS and VDD. |
| 9 | A1 | input | Address 1 input for the I2C interface, which is combined with the other address pins to complete the device address and allow up to eight devices on one bus. |
| 10 | VDD | power_in | Positive power supply input referenced to VSS; electrical performance may not meet data sheet specifications while VDD is below 2.7V. |
