DIN

Digital Serial-Data Input

20

Digital Power-Supply Input. Bypass to DGND with a 0.1µF capacitor.

21

DGND

Digital Ground

22

LDAC

Active-Low Digital Load DAC Input. Drive this asynchronous input low to transfer the contents of the

input register to their respective DAC registers and set all DAC outputs accordingly.

23

CLR

Active-Low Digital Clear Input. Drive this asynchronous input low to clear the contents of the input and

DAC registers and set all the DAC outputs to zero.

24

GS

Ground-Sense Analog Input. Offsets the DAC amplifier outputs by ±0.5V to compensate for a remote

system ground potential difference.
