MCP4811T-E 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 supply voltage input, 2.7V to 5.5V relative to VSS, with a 0.1 µF ceramic bypass to ground recommended plus an additional 10 µF tantalum in parallel. |
| 2 | CS | input | Chip Select input that requires an active low to enable serial clock and data functions. |
| 3 | SCK | input | SPI compatible serial clock input. |
| 4 | SDI | input | SPI compatible serial data input. |
| 5 | LDAC | input | DAC synchronization input: when low, the input register is transferred to the output register and VOUT is updated, and it can be tied to VSS to update VOUT on the rising edge of CS. |
| 6 | SHDN | input | Hardware Shutdown input. |
| 7 | VSS | power_in | Ground reference point and analog ground/current return path for the device, which must be connected to a low-impedance ground plane. |
| 8 | VOUT | output | DAC analog output with a full-scale range from VSS to G*VREF (G = 1x or 2x) that cannot go higher than VDD. |
