TYPICAL PERFORMANCE CHARACTERISTICS
CLK: The Serial Interface Clock.
D
CS/LD: The Serial Interface Enable and Load Control.
When CS/LD is low the CLK signal is enabled, so the data
can be clocked in. When CS/LD is pulled high data is
loaded from the shift register into the DAC registers,
updating the DAC outputs.
