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.
