REFOUT (Pin 15): Internal Reference Voltage Output.
Nominal value is 2.5V. Requires a 0.1
F bypass capacitor
to AGND.
IREFIN (Pin 16): Reference Input Current. Nominal value is
1.25mA for IFS = 10mA. IFS = IREFIN 8.
AGND (Pin 17): Analog Ground.
LADCOM (Pin 18): Attenuator Ladder Common. Normally
tied to GND.
IOUT B (Pin 19): Complementary DAC Output Current. Full-
scale output current occurs when all data bits are 0s.
IOUT A (Pin 20): DAC Output Current. Full-scale output
current occurs when all data bits are 1s.
COMP1 (Pin 21): Current Source Control Amplifier Com-
pensation. Bypass to VSS with 0.1F.
COMP2 (Pin 22): Internal Bypass Point. Bypass to VSS
with 0.1
F.
VSS (Pin 23): Negative Supply Voltage. Nominal value is
– 5V.
DGND (Pin 24): Digital Ground.
VDD (Pin 25):Positive Supply Voltage. Nominal value is 5V.
CLK (Pin 26): Clock Input. Data is latched and the output
is updated on positive edge of clock.
DB11 to DB0 (Pins 27, 28, 1 to 10 ): Digital Input Data Bits.
