No Connection
Analog Supply (9.0V to 15.5V)
High-Voltage Reference for V
Low-Voltage Reference for V
Ground
Select Inputs. When the Control register [1,0] = 00, S0 and S1 are used to select
DAC input data from EEPROM.
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.
I
Digital Supply (2.7V to 5.5V)
Compensation Capacitor Input. Connect VCAP to GND through a 0.1μF capacitor.
