## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply input operating in the range of 2.7V to 5.5V. |
| 2 | VREF | power_in | Reference voltage input with impedance of 62kΩ and acceptable input range from 0V to VDD. |
| 3 | VOUTB | output | Analog output voltage from DAC B with output range from 0V to VREF. |
| 4 | VOUTA | output | Analog output voltage from DAC A with output range from 0V to VREF. |
| 5 | SYNC | input | Level-triggered SYNC input (active LOW) for frame synchronization; data transferred on falling edges of SCLK; Schmitt-Trigger logic input. |
| 6 | SCLK | input | Serial Clock Input capable of data rates up to 30MHz at VDD=5V; Schmitt-Trigger logic input. |
| 7 | DIN | input | Serial Data Input; data clocked into 24-bit input shift register on falling edge of serial clock input; Schmitt-Trigger logic input. |
| 8 | GND | power_in | Ground reference point for all circuitry on the part. |
