DESCRIPTION
Power supply input, 2.7 V to 5.5 V.
Reference voltage input.
Feedback connection for the output amplifier. For voltage output operation, tie to V
OUT
externally.
Analog output voltage from DAC. The output amplifier has rail-to-rail operation.
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 24th clock (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 DAC8551).
Serial clock input. Data can be transferred at rates up to 30 MHz.
Serial data input. Data is clocked into the 24-bit input shift register on each falling edge of the serial clock input.
Ground reference point for all circuitry on the part.
