A1_EE

I²C Device Address 1 for EEMEM.

I²C Device Address 1 for RDAC.

I²C Device Address 0 for RDAC.

Resets the scratchpad register with current contents of the EEMEM register. Factory defaults to midscale before

any programming.

A1_RDAC

A0_RDAC

Write Protect. When active low, WP prevents any changes to the present register contents, except that RESET

and Commands 1 and 8 still refresh the RDAC register from EEMEM.

Serial Input Register Clock. Shifts in one bit at a time on the positive clock edges.

Serial Data Input. Shifts in one bit at a time on the positive clock edges. The MSB is loaded first.

Ground. Logic ground reference.

Negative Supply. Connect to 0 V for single-supply applications.
