PIN DESCRIPTIONS
PIN NAME
DESCRIPTION
1
V_DD Power supply input, 2.7V to 5.5V.
2 V_REF Reference voltage input/output.
3
V_FB Feedback connection for the output amplifier. For voltage output operation, tie to V_OUT externally.
4 V_OUT 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

SYNC
LOW, it enables the input shift register, and data is sampled on subsequent falling clock edges. The DAC output updates
following the 24th clock. If SYNC is taken HIGH before the 24th clock edge, the rising edge of SYNC acts as an interrupt,
and the write sequence is ignored by the DAC8560. Schmitt-Trigger logic Input.
6 SCLK Serial clock input. Schmitt-Trigger logic input.
7
D_IN
Serial data input. Data is clocked into the 24-bit input shift register on each falling edge of the serial clock input.
Schmitt-Trigger logic Input.
8 GND Ground reference point for all circuitry on the part.
