PIN FUNCTION DESCRIPTIONS

Function

Analog output voltage from DAC. The output amplifier has rail-to-rail operation.

Ground reference point for all circuitry on the part.

Power Supply Input. These parts can be operated from +2.5 V to +5.5 V and VDD should be de-

coupled to GND.

Serial Data Input. This device has a 16-bit shift register. Data is clocked into the register on the

falling edge of the serial clock input.

Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial clock

input. Data can be transferred at rates up to 30 MHz.

Level triggered control input (active low). This is the frame synchronization signal for the input

data. When SYNC goes low, it enables the input shift register and data is transferred in on the

falling edges of the following clocks. The DAC is updated following the 16th clock cycle unless

SYNC is taken high before this edge in which case the rising edge of SYNC acts as an interrupt and

the write sequence is ignored by the DAC.
