Power supply input. Must be decoupled to GND.
Channel A analog output voltage.
Channel B analog output voltage.

Ground reference for all on-chip circuitry.
Unbuffered reference voltage shared by all channels. Must be decoupled
to GND.
Serial data input. Data is clocked into the 16-bit shift register on the falling
edges of SCLK after the fall of SYNC.
Frame synchronization input for the data input. When this pin goes low, it
enables the input shift register and data is transferred on the falling edges
of SCLK. The DAC is updated on the 16th clock cycle unless SYNC is
brought high before the 16th clock, in which case 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.
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.
