VDD
Power
Analog Supply (9.0V to 15.5V)
7
VRH
Ref Input
High-Voltage Reference for VCOM DAC

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.

SCL
Input
I2C Serial Clock Input
17, 47
VCC
Power
Digital Supply (2.7V to 5.5V)

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