MCP4561-502E from Microchip Tech, in a MSOP-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 | HVC/A0 | input | High Voltage Command / Address 0 input for I2C interface; latched at POR/BOR; high-voltage tolerant to 12.5V; used to enable WiperLock and Write Protect control features. |
| 2 | SCL | input | Serial Clock input for I2C interface; accepts external clock signals in slave mode; high-voltage tolerant to 12.5V; supports 100 kHz, 400 kHz, 1.7 MHz, and 3.4 MHz operation. |
| 3 | SDA | bidirectional | Serial Data I/O for I2C interface with open-drain N-channel driver output; high-voltage tolerant to 12.5V; maximum output current sunk by pin is 25 mA. |
| 4 | VSS | power_in | Ground reference for device; maximum current out of VSS pin is 100 mA. |
| 5 | P0A | passive | Potentiometer 0 Terminal A, fixed connection to Full-Scale wiper value (0x100 for 8-bit devices); voltage range VSS to VDD; maximum current ±2.5 mA. |
| 6 | P0W | passive | Potentiometer 0 Wiper Terminal (adjustable contact); voltage range VSS to VDD; typical wiper resistance 75 Ω; maximum current ±2.5 mA. |
| 7 | P0B | passive | Potentiometer 0 Terminal B, fixed connection to Zero-Scale wiper value (0x00); voltage range VSS to VDD; maximum current ±2.5 mA. |
| 8 | VDD | power_in | Positive Power Supply Input, operating range 2.7V to 5.5V; maximum current into VDD pin is 100 mA; requires 0.1 µF bypass capacitor placed within 4 mm of pin. |
