Pinout
8| Pin | Name | Functions | Notes |
|---|---|---|---|
| VDD | Power supply input | POWER | 2.7 V to 5.5 V |
| REF | Reference voltage input | GPIO | |
| FB | Feedback connection for the output amplifier | GPIO | |
| OUT | Analog output voltage from DAC | GND | Rail-to-rail operation |
| GND | Ground reference point for all circuitry on the part | GND | |
| DIN | Serial data input | GPIO | Data is clocked into the 24-bit input shift register on each falling edge of the serial clock input. Schmitt-Trigger logic input. |
| SCLK | Serial clock input | SPI | Data can be transferred at rates up to 30-MHz Schmitt-Trigger logic input. |
| SYNC | Level-triggered control input (active LOW) | GPIO | This is the frame synchronization signal for the input data. When SYNC goes LOW, it enables the input shift register and data is transferred in on the falling edges of the following clocks. |
