CS/LD (Pin 8): The TTL Level Input for the Serial Interface
Enable and Load Control. When CS/LD is low, the CLK
signal is enabled so the data can be clocked in. When
CS/LD is pulled high, data is loaded from the shift register
into the DAC register, updating the DAC output.
CLR (Pin 9): The DAC is cleared to V
pulled low. It should be logic high for normal operation.
RSTOUT (Pin 10): The logic output pin that goes active
when any of the supplies drop below 2.5V. This pin is
active low.
REFHI (Pin 11): The Reference Input Pin. The DAC is
capable of 4-quadrant multiplying; this pin can swing
from 4.5V to – 4V.
