Analog Input
to GND.
Serial Data Input. Data is clocked into the 16-bit shift register on the falling
Digital Input
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
Digital Input
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
Digital Input
falling edges of this pin.
Exposed die attach pad can be connected to ground or left floating.
Ground
Soldering the pad to the PCB offers optimal thermal performance and
enhances package self-alignment during reflow.
