Pin Description
PIN NAME TYPE FUNCTION
1–5, 9, 10,
46, 48
N.C. — No Connection
6, 23, 43 V
DD
Power Analog Supply (9.0V to 15.5V)
7 VRH Ref Input High-Voltage Reference for V
COM
DAC
8 VRL Ref Input Low-Voltage Reference for V
COM
DAC
11, 18, 19,
21, 22, 42
GND Power 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.

CC
Power Digital Supply (2.7V to 5.5V)
20 VCAP Input Compensation Capacitor Input. Connect VCAP to GND through a 0.1μF capacitor.
24–30 GM1–GM7 Output Low-Voltage Gamma Analog Outputs
31–37 GM8–GM14 Output High-Voltage Gamma Analog Outputs
38 GLM Ref Input Reference for Low-Voltage Gamma DAC
39 GLL Ref Input Reference for Low-Voltage Gamma DAC
40 GHM Ref Input Reference for High-Voltage Gamma DAC
41 GHH Ref Input Reference for High-Voltage Gamma DAC
44 V
