pin Functions

CS/LD (Pin 1): Serial Interface Chip Select/Load Input.

REF (Pin 4): Reference Voltage Input. 0V ≤ V ≤ V .

REF CC

When CS/LD is low, SCK is enabled for shifting data on

(Pin8,Pin5):DACAnalogVoltageOutputs.

OUTA OUTB

The output range is

D into the register. When CS/LD is pulled high, SCK is

GND (Pin 7): System Ground.

the D pin is shifted into the 16-bit register on the rising

edge of SCK. CMOS and TTL compatible.
