Frame Synchronization Input. When this pin goes low, data is
written into the DAC's input shift register on the falling edges of
SCLK. After the 16th falling edge of SCLK, a rising edge of SYNC
causes the DAC to be updated. If SYNC is brought high before the
15th falling edge of SCLK, the rising edge of SYNC acts as an
interrupt and the write sequence is ignored by the DAC.
Serial Clock Input. Data is clocked into the input shift register on
the falling edges of this pin.
Serial Data Input. Data is clocked into the 16-bit shift register on
the falling edges of SCLK after the fall of SYNC.

SCLK cycles.
Exposed die attach pad can be connected to ground or left floating.
Soldering the pad to the PCB offers optimal thermal performance
and enhances package self-alignment during reflow.
