## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | REF | bidirectional | Internal 2.5V precision reference output (default mode) or external reference input (1.25V to 5.5V input range per Recommended Operating Conditions). |
| 2 | OUT0 | output | Analog output voltage from DAC channel 0; output range 0V to VREF, 0V to 2×VREF, or 0V to ½×VREF configurable via BUFF-GAIN and REF-DIV bits. |
| 3 | OUT1 | output | Analog output voltage from DAC channel 1; output range 0V to VREF, 0V to 2×VREF, or 0V to ½×VREF configurable via BUFF-GAIN and REF-DIV bits. |
| 4 | OUT2 | output | Analog output voltage from DAC channel 2; output range 0V to VREF, 0V to 2×VREF, or 0V to ½×VREF configurable via BUFF-GAIN and REF-DIV bits. |
| 5 | OUT3 | output | Analog output voltage from DAC channel 3; output range 0V to VREF, 0V to 2×VREF, or 0V to ½×VREF configurable via BUFF-GAIN and REF-DIV bits. |
| 6 | GND | power_in | Ground reference point for all circuitry on the device. |
| 7 | VDD | power_in | Analog supply voltage 2.7V to 5.5V; bypass with 1-10µF and 0.1µF capacitors per Power Supply Recommendations section. |
| 8 | OUT4 | output | Analog output voltage from DAC channel 4; output range 0V to VREF, 0V to 2×VREF, or 0V to ½×VREF configurable via BUFF-GAIN and REF-DIV bits. |
| 9 | OUT5 | output | Analog output voltage from DAC channel 5; output range 0V to VREF, 0V to 2×VREF, or 0V to ½×VREF configurable via BUFF-GAIN and REF-DIV bits. |
| 10 | OUT6 | output | Analog output voltage from DAC channel 6; output range 0V to VREF, 0V to 2×VREF, or 0V to ½×VREF configurable via BUFF-GAIN and REF-DIV bits. |
| 11 | OUT7 | output | Analog output voltage from DAC channel 7; output range 0V to VREF, 0V to 2×VREF, or 0V to ½×VREF configurable via BUFF-GAIN and REF-DIV bits. |
| 12 | CS | input | Active-low chip select; enables serial interface input shift register when CS driven low for 24-bit or 32-bit (with CRC enabled) data transfer. |
| 13 | SCLK | input | Serial interface clock input; data clocked into shift register on falling edge of SCLK; maximum frequency 50MHz. |
| 14 | SDI | input | Serial interface data input; MSB-first data clocked into input shift register on each falling edge of SCLK. |
| 15 | SDO/ALARM | output | Serial interface data output (default, high-impedance when CS high) or configurable as open-drain alarm output for CRC or reference error indication (requires 10kΩ pull-up to VIO). |
| 16 | VIO | power_in | I/O supply voltage 1.7V to 5.5V; sets serial interface logic levels and requires 0.1µF bypass capacitor. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
