MCP4922-E from Microchip Tech, in a SOIC-14. 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 | VDD | power_in | Supply voltage input, 2.7V to 5.5V single supply operation. |
| 2 | NC | unconnected | No connection. |
| 3 | CS | input | Chip select input, active low to enable serial clock and data functions. |
| 4 | SCK | input | SPI compatible serial clock input, supports up to 20 MHz clock frequency. |
| 5 | SDI | input | SPI compatible serial data input, data clocked in on rising edge of SCK. |
| 6 | NC | unconnected | No connection. |
| 7 | NC | unconnected | No connection. |
| 8 | LDAC | input | Latch DAC synchronization input, transfers DAC input registers to output registers when low. |
| 9 | SHDN | input | Hardware shutdown input, active low shuts down both DAC channels and configures output to 500 kΩ high impedance. |
| 10 | VOUTB | output | DAC B analog output, rail-to-rail output from 0V to VDD with maximum settling time of 4.5 µs. |
| 11 | VREFB | input | DAC B reference voltage input, range VSS to VDD, sets full-scale output range for DAC channel B. |
| 12 | VSS | power_in | Ground reference point for all circuitry on the device, analog ground with low-impedance connection required. |
| 13 | VREFA | input | DAC A reference voltage input, range VSS to VDD, sets full-scale output range for DAC channel A. |
| 14 | VOUTA | output | DAC A analog output, rail-to-rail output from 0V to VDD with maximum settling time of 4.5 µs. |
