Ground
12
S1
Input
13
S0
Input
Select Inputs. When the Control register [1,0] = 00, S0 and S1 are used to select
DAC input data from EEPROM.
14
LD
Input
Latch Data Input. When LD is low, Latch B retains existing data (acts as a latch).
When LD is high, the input to Latch B data flows through to the output and updates
the DACs asynchronously.

VCAP
Input
Compensation Capacitor Input. Connect VCAP to GND through a 0.1μF capacitor.
