Pinout
9| Pin | Name | Functions | Notes |
|---|---|---|---|
| 1 | VDD | POWER | Analog supply voltage (2.7 V to 5.5 V) |
| 2 | VOUT | ADC | Analog output voltage from the DAC |
| 3 | NC | GPIO | No connection. Leave floating. |
| 4 | AGND | GND | Ground reference point for all circuitry on the device |
| 5 | SPI2C | GPIO | Interface select pin. Digital interface in SPI mode if SPI2C = 0, digital interface in I2C mode if SPI2C = 1. |
| 6 | SCLK/SCL | SPII2C | Serial interface clock. SPI or I2C mode. |
| 7 | SYNC/A0 | GPIO | Active low serial data enable in SPI mode, four-state address input 0 in I2C mode. |
| 8 | SDIN/SDA | SPII2C | Serial interface data input. SPI mode: Data are clocked into the input shift register on each falling edge of the SCLK pin. I2C mode: Data are clocked into or out of the input register. |
| 10 | VREFIO | ADC | Reference output voltage pin when using internal reference, reference input to device when operating with external reference. |
